The purpose of this study was to investigate the effects of radical prostatectomy (RP) for prostate cancer, transurethral resection of the prostate (TURP) for benign prostate hyperplasia (BPH), and the alterations induced by ageing on quality of life, urinary and sexual function, and bother. We evaluated 283 patients who filled in and returned the questionnaire used. A total of 105 were treated with RP and were selected prostate cancer patients with localised disease without recurrences. An additional 98 underwent TURP for BPH and a third group consisted of 80 apparently healthy men. The general quality of life was estimated by the Rand 36-Item Health Survey 1.0. Urinary function was estimated by the AUA Symptom Index and the UCLA Prostate Cancer Index (urinary function and bother scale). Sexual function and bother, were explored using the Brief Male Sexual Function Inventory for Urology. Patient outcome 2 years post treatment was compared to the pre-treatment status and to that of the matched control population. General quality of life was not affected by RP or TURP, with the exception of an increase in the emotional/well being domain in RP patients to control group levels. After RP there was more bother reported for the urinary function than urinary malfunction itself, while TURP, as expected, restored urinary function and bother to normal population norms. Elderly males had urinary function and bother similar to the operated patients. Estimating sexual function on RP patients, erectile dysfunction (ED) predominates, leading to decreased sexual life. TURP marginally affects sexual life, mainly due to the loss of ejaculation, while in men from the control group, sexual function, although affected, was still present. [ABSTRACT FROM AUTHOR]

This study assesses the correlation of p53 immunoreactivity and DNA ploidy status with biochemical recurrence after radical prostatectomy. p53 protein expression and DNA ploidy were evaluated on 84 archival paraffin-embedded radical prostatectomy specimens. Patients were divided into two groups: those with low (38/84, 45%) and those with high (46/84, 55%) p53 immunoreactivity. The results were correlated with Gleason score, stage and serum PSA. Kaplan-Meier biochemical recurrence free survival and the Cox hazard-regression model were used for analysis. Multivariate analysis revealed p53, DNA ploidy, Gleason score, PSA and stage to be independent prognostic factors in this order. Kaplan-Meier analysis showed a significant difference in biochemical recurrence when p53 high expression and DNA aneuploidy were combined. The results of this study suggest that stratification for p53 expression and DNA ploidy status can provide additional prognostic information for patients with prostate carcinoma after radical prostatectomy.

Our aim was to compare the stone free rate and the financial cost between in situ and after manipulation shock wave lithotripsy (SWL) for proximal ureteral stones. A total of 130 patients with proximal ureteral stones were prospectively randomized into two groups. Sixty-five patients (group 1) underwent SWL in situ and 65 patients (group 2) underwent SWL after an attempt was made to push back the stone into the kidney with the help of a ureteral catheter. The mean per person financial cost of both techniques was estimated after a follow up period of 3 months. The stone free rate 1 month post treatment was 83% (54/65 patients) for group 1 and 95% (62/65) for group 2. The higher success rate at 1 month for the pushback group was statistically significant (P=0.04) but was correlated with a higher cost (€852 vs €1,008.5). Fifteen additional sessions of SWL and follow up visits were needed in group 1, therefore making the final costs of the two therapeutic pathways almost equal (€1,050.9 vs €1,088.9), with no great difference in the overall fragmentation rates at 3 months between groups (94% and 97%, respectively). Stone manipulation offers higher stone free rates faster than in situ extracorporeal SWL, but is more expensive. This disparity in cost is diminished when costs are corrected for follow-ups and treatment of complications. [ABSTRACT FROM AUTHOR]

Laser enucleation of the prostate (LEP) and robotic-assisted simple prostatectomy (RASP) are two main treatment methods for large benign prostatic hyperplasia (BPH), but the superiority between these two methods in treating large BPH is currently unclear. This study aims to conduct a meta-analysis to compare the efficacy and the safety of LEP and RASP in treating large BPH. We systematically searched the PubMed, Embase, and Cochrane Library databases for studies that compared safety and efficacy outcomes of both LEP and RASP. Review Manager 5.3 was used for the meta-analysis. Six studies with a total of 1235 patients were included in the analysis. Resected adenoma weight was similar in LEP than RASP group. Operative time [mean difference (MD) − 67.96; 95% confidence interval [CI] − 131.66 to − 4.25; p = 0.04], catheterization time (MD -6.31; 95% CI − 9.44 to − 3.18; p < 0.0001), and length of stay (MD − 2.44; 95% CI − 3.55 to − 1.34; p < 0.0001) were lower in LEP. The International Prostate Symptom Score, maximum urinary flow rate, prostate-specific antigen, and post-void residual urine volume were also comparable between two groups. Furthermore, LEP demonstrated lesser hemoglobin decrease (MD − 0.50; 95% CI − 0.96 to − 0.05; p = 0.03), lower blood transfusion rate [odd ratio (OR) 0.23, 95% CI 0.08–0.66; p = 0.006], and lower rate of Clavien–Dindo Grade ≥ 3 complications (OR 0.435, 95% CI 0.189–0.998; p = 0.049). Finally, there was no significant difference in overall complications between two groups. Current evidence shows that LEP offers favorable perioperative outcomes compared with RASP. However, there was no conclusive evidence that LEP was advantaged in terms of efficacy outcomes. [ABSTRACT FROM AUTHOR]

Purpose: Anatomical characteristics of the greater palatine foramen (GPF) are essential during the greater palatine nerve block application to anesthetize maxillary teeth, gums, midface, and nasal cavities. The position of GPF is usually described in relation to adjacent anatomical structures. This investigation aims to examine the morphometric relationships of GPF and closely determine its position. Methods: The study included 87 skulls (174 foramina). They were photographed in a horizontal position with bases facing up. The digital data were processed in the ImageJ 1.53n software. Results: The average distance of the GPF from the median palatine suture was 15.94 mm. In relation to the posterior border of the bony palate, the distance was 2.05 mm. Statistical significance was found in comparing the angle between the GPF, incisive fossa, and the median palatine suture between the sides of the skulls (p = 0.02). Comparing tested parameters between males and females showed significant differences in GPF–MPS (p = 0.003) and GPF–pb (p = 0.012), with lower values in females. The most significant percentage of skulls (77.01%) had the GPF located at the level of the third molar. The most significant number of bony palates had one lesser opening (60.91%) on the left side. Conclusion: GPF is located at the level of the maxillary third molar in most of the examined palates. Knowledge of the anatomical position of the greater palatine foramen and its variations is the basis for successfully implementing anesthesia and various surgical interventions.

Laparoscopic simple prostatectomy (LSP) and robot-assisted simple prostatectomy (RASP) are important approaches for large benign prostatic hyperplasia (BPH), though it is still unclear which is superior. This study aimed to perform a pooled analysis to compare the safety and efficacy profiles of LSP and RASP. We systematically searched the databases of Science, PubMed, Embase, Web of Science, and Cochrane Library database for randomized controlled trials (RCTs) and non-RCTs, comparing LSP to RASP. The principal outcomes included perioperative, functional and complications variables. The results are presented as odds ratio (OR) or weighted mean difference (WMD) with 95% confidence intervals (CI) of dichotomous and continuous variables. Five comparative trials involving 1928 patients were included. RASP demonstrated a shorter length of hospital stay compared to LSP (WMD 1.20 days, 95% CI 0.09, 2.32; p = 0.03). However, there was no difference between the two groups regarding operative time, estimated blood loss, catheterization time and complications. Moreover, RASP had a higher maximum flow rate (Qmax) (WMD − 2.15 mL/s, 95% CI − 3.75, − 0.55; p = 0.0009) and comparable international prostate symptom score (IPSS) and sexual health inventory (SHIM) in men with LSP. The results of this study demonstrated that RASP offered comparable efficacy and safety to LSP, while maintaining a superior perioperative and functional profile. However, treatment selection should also be based on the availability and experience of the operator. [ABSTRACT FROM AUTHOR]

Background: Horseshoe kidney is one of the most common congenital renal fusion anomalies and is characterized by abnormalities in the position, rotation, vascular supply, and ureteral anatomy of the kidney. When performing surgery for colorectal cancer in patients with horseshoe kidneys, anatomical identification is important to avoid organ injuries. Several reports on surgery for colorectal cancer with horseshoe kidneys have described the usefulness of three-dimensional (3D) computed tomography (CT) angiography for detecting abnormalities in vascular supply. However, few reports have focused on the prevention of ureteral injury in surgery for colorectal cancer with horseshoe kidney, despite abnormalities in the ureteral anatomy. Here, we report a case in which laparoscopic sigmoid colon resection for sigmoid colon cancer with a horseshoe kidney was safely performed using fluorescent ureteral catheters. Case presentation: A 60-year-old Japanese man presented to our hospital testing positive for fecal occult blood. Colonoscopy revealed sigmoid colon cancer, and CT confirmed a horseshoe kidney. The 3D-CT angiography showed aberrant renal arteries from the aorta and right common iliac artery, and the left ureter passed across the front of the renal isthmus. A fluorescent ureteral catheter was placed in the left ureter before the surgery to prevent ureteral injury. Laparoscopic sigmoid colon resection with D3 lymph node dissection was performed. The fluorescent ureteral catheter enabled the identification of the left ureter that passed across the front of the renal isthmus and the safe mobilization of the descending and sigmoid colon from the retroperitoneum. The operative time was 214 min, with intraoperative bleeding of 25 mL. The patient's postoperative course was good: no complications arose and she was discharged on the seventh postoperative day. Conclusion: In patients with horseshoe kidney, the use of fluorescent ureteral catheters and 3D-CT angiography enables safer laparoscopic surgery for colorectal cancer. We recommend the placement of fluorescent ureteral catheters in such surgeries to prevent ureteral injury. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the effectiveness and safety of non-papillary prone PCNL for the treatment of patients with renal abnormalities. Methods: An observational retrospective cohort study including PCNL cases of patients with renal abnormalities was performed. The following inclusion criteria were applied: renal stones > 1.5 cm with maximal diameter, anatomical malformations of affected kidney (malrotated kidneys, horseshoe kidneys and kidneys with complete duplicated systems, medullary sponge kidney), patients treated with standard (30Fr) PCNL or mini-PCNL (22Fr). The lithotripsy was performed using the Lithoclast Master or the Lithoclast® Trilogy (EMS Medical, Nyon, Switzerland). Results: Overall, 57 patients, 35 males, and 22 females with any renal malformation underwent non-papillary prone PCNL. Our study included 25 patients with horseshoe kidneys, 21 with malrotated kidneys, 9 with kidneys with duplicated pelvicalyceal systems and 2 with medullary sponge kidneys. The mean cumulative stone size was 36 ± 1.4 mm and most of the stones were in the lower calyceal group (36.9%) and in the pelvis (27.2%). The stone-free rate (SFR) was 84.2% and the mean hospitalization time was 2.7 ± 0.7 days. In total, postoperative complications were developed in six patients (10.5%), half of them presenting fever and the other half requiring blood transfusion (Grade II). Conclusion: The PCNL is the method of choice for treating large stones in anomalous kidneys. The generally accepted panacea that only a papillary puncture is safe is questioned by our results. Based on our experience, a non-papillary puncture proved to be a safe and effective procedure. [ABSTRACT FROM AUTHOR]

Purpose: Accurate knowledge of greater palatine foramen (GPF) and greater palatine canal (GPC) anatomy is necessary to avoid injury to the greater palatine artery (GPA) when performing a variety of anesthesiologic, dental or surgical procedures. The aim of this paper was to perform a systematic review and meta-analysis of literature on the anatomy and localization of bony structures associated with the GPA, namely the GPF and GPC. Methods: A systematic literature search was performed using PubMed, Embase, ScienceDirect, and Web of Science databases. Seventy-five studies were included in the meta-analysis (n = 22,202 subjects). Results: The meta-analysis showed that the GPF is positioned 17.21 mm (95% CI = 16.34–18.09 mm) from the posterior nasal spine, 2.56 mm (95% CI = 1.90–3.22 mm) from the posterior border of the hard palate, 46.24 mm (95% CI = 44.30–48.18 mm) from the anterior nasal spine, 15.22 mm (95% CI = 15.00–15.43 mm) from the midline maxillary suture, 37.32 mm (95% CI = 36.19–38.45 mm) from the incisive foramen, and opposite the third maxillary molar (M3) in 64.9% (58.7–70.7%) of the total population. Conclusion: An up-to-date, comprehensive analysis of GPF and GPC clinical anatomy is presented. The results from this evidence-based anatomical study provides a unified set of data to aid clinicians in their practice. [ABSTRACT FROM AUTHOR]

Purpose of Review: This study aimed to review recent evidence on conservative non-surgical options for erectile dysfunction (ED) in men. A narrative review of the literature was performed. A comprehensive search in the MEDLINE, Embase, and Cochrane databases was done. Papers in English language, published from May 2017 until May 2022, were included. Papers reporting basic research or animal research were excluded, as long as reviews or meta-analyses. Congress reports, clinical cases, or clinical trials protocols with no results were also excluded. Recent Findings: We found a multitude of different treatment modalities for ED. We must take into account the type of patient, their comorbidities, the origin of their ED, and its severity in order to reproduce effective results using these therapies. Some of the treatments show good results with a good level of evidence (new IPDE5 formulations, intracavernous injections, shock wave therapy, hormonal theraphy, psycho-sexual theraphy). However, others (some new molecules, stem cell theraphy, platelet-rich plasma injections, oxygenation-based therapy, nutraceuticals), although some of them present promising results, require randomized studies with a larger number of patients and a longer follow-up time to be able to establish firm recommendations. Summary: Regarding the conservative treatment of erectile dysfunction, in recent years, some therapies have been consolidated as effective and safe for certain types of patients. On the other hand, other treatment modalities, although promising, still lack the evidence and the necessary follow-up to be recommended in daily practice. [ABSTRACT FROM AUTHOR]

Impacted stones typically make it difficult to perform ureteroscopic lithotripsy (URSL), so it is useful to preoperatively predict such impaction. We focused on CT attenuation values of the ureter above and below the stone ('HU above' and 'HU below') and calculated their ratio (HAB ratio; HU above/HU below ratio). The aim was to investigate whether HAB ratio could predict impacted stones preoperatively. Between 2011 and 2019, 171 patients from our hospital that had URSL for ureteral stones with pretreatment non-contrast computed tomography (NCCT) were retrospectively identified. Ureteral wall thickness (UWT), ureteral wall volume (UWV) and HAB ratio ('HU above' divided by 'HU below') were recorded. Impacted stones were defined as fixed stones that did not move by means of ureteroscopic manipulation or water pressure. Of the 171 procedures, 46 (27%) involved patients with impacted stones. Comparing patient characteristics and stone parameters according to impaction status, factors with significant difference included grade of hydronephrosis, UWT, and HAB ratio (all P < 0.01). Multivariate analysis indicated that significant independent predictors of impacted stones were thicker UWT and lower HAB ratio (all P < 0.01). HAB ratio was a significant preoperative predictor of stone impaction in patients undergoing URSL for ureteral stones. HAB ratio may be informative for selecting the treatment and preoperative preparations. [ABSTRACT FROM AUTHOR]

Purpose: Although lumbar discectomy is the most common procedure in spine surgery, reports about anatomical relations between discs and prevertebral vessels are limited. Aim of this research was to investigate morphometric of the lumbar region and the relations between intervertebral discs (IVDs) and abdominal aorta. Methods: 557 abdominal computed tomography scans were assessed. For each spinal column level from Th12/L1 down to L4/L5, we investigated: intervertebral disc's and vertebra's height, width, length, and distance from aorta or common iliac artery (CIA). Those arteries were also measured in two dimensions and classified based on location. Results: 54.58% of patients were male. There was a significant difference in arterial-disc distances (ADDs) between genders at the levels: L1/L2 (1.32 ± 1.97 vs. 0.96 ± 1.78 mm; p = 0.0194), L2/L3 (1.97 ± 2.16 vs. 1.15 ± 2.01 mm; p < 0.0001), L3/L4 (2.54 ± 2.78 vs. 1.71 ± 2.61 mm; p = 0.0012), also for both CIAs (left CIA 3.64 ± 3.63 vs. 2.6 ± 3.06 mm; p = 0.0004 and right CIA: 7.96 ± 5.06 vs. 5.8 ± 4.57 mm; p < 0.001)—those ADDs were higher in men at all levels. The length and width of IVD increased alongside with disc level with the maximum at L4/L5. Conclusion: Bifurcations of the aorta in most cases occurred at the L4 level. Collected data suggest that at the highest lumbar levels, there is a greater possibility to cause injury of the aorta due to its close anatomical relationship with discs. Females have limited, in comparison to males, ADD at L1/L2, L2/L3, and L3/L4 levels what should be taken into consideration during preoperative planning of surgical intervention.

Renal fusion anomalies are common congenital anomalies of the urogenital tract and have their genesis in the early embryonic period. They are classified into partial fusion anomalies (e.g., crossed fused ectopia, and horseshoe kidney) and complete fusion anomalies (e.g., fused pelvic kidney). Horseshoe kidney is the most common renal fusion anomaly and is characterized by the presence of two distinct functioning kidneys on either side of the vertebral column, with fusion occurring at the inferior poles in majority of the cases. Crossed fused ectopia is characterized by the presence of an ectopic kidney that crosses the midline and fuses with the orthotopic contralateral kidney, whereas fused pelvic (pancake) kidney is a complete fusion anomaly characterized by extensive medial fusion of both kidneys in the pelvis. Fusion anomalies are often associated with abnormalities of renal rotation, migration, and vascular supply, which predispose the kidneys to a number of complications and create difficulty during retroperitoneal surgeries and interventions. They are also associated with other congenital abnormalities of the urogenital tract, gastrointestinal tract, cardiovascular system, and skeletal system. Hence, a thorough understanding of the etiopathogenesis and radiological features of fusion anomalies is important for directing patient management. This review summarizes the embryological basis, clinical presentation and imaging approach to renal fusion anomalies, followed by detailed anatomical and radiological description of the morphological types, and the complications associated with these anomalies.

Holmium laser enucleation of the prostate (HoLEP) is a valid treatment option to relieve bladder outlet obstruction in patients with large prostate volumes (PV). Its efficacy, tolerability, and safety are comparable to the ones of other laser treatments of the prostate and resection techniques. However, safety and efficacy of HoLEP have not been compared between patients with and without preoperative urinary retention. We included 350 patients (mean age 71.2 years) who had undergone HoLEP due to lower urinary tract symptoms (LUTS) or urinary retention caused by prostatic hyperplasia. We evaluated the differences in peri- and postoperative outcomes and complications between patients with and patients without preoperative urinary retention. The mean PV was 115 cm3. PV was > 100 cm3 in 61.9% and < 100 cm3 in 38.1% of the patients. Perioperative complications occurred in 23 patients (6.6%), 15 of which (4.3%) required operative revision. We found no significant differences in terms of complication rates between patients with PV > 100 cm3 and patients with PV < 100 cm3. Mean catheterization-duration was 3.3 days. Preoperatively, 140 patients (40%) had a suprapubic or transurethral indwelling catheter; they did not differ from patients without preoperative catheter regarding postoperative catheter removal success rate, early postoperative complications, and functional outcomes. Prostate cancer was diagnosed in 43 patients (12.3%). Median postoperative PSA-decline was 6.1 ug/l (89.8% drop). HoLEP is a safe and effective treatment for patients with LUTS or urinary retention and large PV. PV > 100 cm3 was not associated with higher complication rates or successful catheter-removal. Furthermore, functional outcomes were independent of preoperative catheterization. [ABSTRACT FROM AUTHOR]

The benefit of transurethral laser prostatectomy over open simple prostatectomy (OSP) is controversial in aged symptomatic benign prostatic hyperplasia (BPH) patients with large volume prostates, and the aim of this study is to compare the safety and efficiency of these two methods. Meta-analysis was applied using the Review Manager V5.3 software and the retrieved randomized controlled clinical trials (RCTs) comparing transurethral laser prostatectomy with OSP were analyzed for the treatment of large volume prostates from 2000 to 2019 in PubMed, Web of Science, Cochrane, and EMBASE datasets. Five RCTs assessing transurethral laser prostatectomy versus OSP were considered suitable for this meta-analysis, which included a total of 448 patients, with 232 patients undergoing laser and 216 patients undergoing OSP. Compared with OSP, although transurethral laser prostatectomy required a longer operative time (weighted mean difference (WMD) 27.49 mins; 95% confidence interval (CI) 16.54–38.44; P < 0.00001) and obtained a less resected prostate weight (WMD − 11.72 g; 95% CI − 21.75 to − 1.70; P = 0.02), patients undergoing laser prostatectomy benefited from significantly less hemoglobin decline (− 0.97 g/dL; 95% CI − 1.31 to − 0.64; P < 0.00001), shorter time of catheterization (WMD − 3.67 days; 95% CI − 5.60 to − 1.75; P = 0.0002), shorter length of hospital stay (WMD − 4.75 days; 95% CI − 6.57 to − 2.93; P < 0.00001), and less blood transfusion (odds ratio 0.10; 95% CI 0.03 to 0.35; P = 0.0003). During postoperative follow-up, no significant difference was observed between the two groups in IPSS, QoL, Qmax, and PVR. Both transurethral laser prostatectomy and OSP are safe and effective for large prostates that require prostate resection. Taking into account of less blood loss, shorter catheterization time and hospital stay, and less blood transfusion, transurethral laser prostatectomy may be a better treatment for patients with large prostates.

Purpose: To compare long-term outcomes between photoselective vaporization (PVP) and Open simple prostatectomy (OSP) for prostates > 80 cc. Methods: Men operated either by PVP or OSP for BPH > 80 cc were included in two expert centres. Functional and uroflowmetric outcomes were assessed pre- and postoperatively. Data were collected prospectively in the PVP group and retrospectively in the OSP group and compared at long-term follow-up. Complications and re-intervention rates were used as main outcomes. Results: 332 men underwent surgery: 132 PVP were performed in a fist expert-centre and 200 OSP were performed in a second one with a median follow-up of 54 and 48 months, respectively. Mean Prostate volume was similar between OSP and PVP group (119 vs 116 cc). Major complications were more common in the OSP group (12.5 vs 1.5%, p < 0.001). At long-term follow-up, Qmax was higher and PVR was lower (p < 0.05) in the OSP group. IPSS score was similar between groups (p = 0.45) but the Qol was better in the OSP group (0.9 vs. 1.6; p < 0.05). There were more re-interventions in the PVP group compared to OSP (15.2 vs. 0%, p < 0.005). Conclusion: PVP is a good alternative for prostates > 80 cc particularly for fragile patients as it is associated with a lower complication rate. At long-term follow-up, IPSS was similar between groups, but Qol was better in the OSP group. Patients treated by PVP should be informed that they could require reoperation in 15% of the cases.

Purpose: Ileal orthotopic neobladder (IONB) reconstruction is the preferred urinary diversion among selected patients who have undergone radical cystectomy (RC) for bladder cancer (BCa). There is insufficient data regarding patients' quality of life (QoL), sexual and urinary outcomes. Our objectives were to assess QoL in a multicentre cohort study, and to identify related clinical, oncological and functional factors. Methods: Patients who underwent RC with IONB reconstruction for BCa from 2010 to 2017 at one of the three French hospitals completed the following self-reported questionnaires: European Organization for Research and Treatment of Cancer (EORTC) generic (QLQ-C30) and bladder cancer specific instruments (QLQ-BLM30). To assess urinary symptoms, patients completed the Urinary Symptom Profile questionnaire (USP) and a three-day voiding diary. Univariate and multivariate analyses were computed to identify clinical, pathological, and functional predictors of global QoL score. Results: Seventy-three patients completed questionnaires. The median age was 64 years and 86.3% were men. The median interval between surgery and responses to questionnaires was 36 months (range 12–96). Fifty-five percent of patients presented a high global QoL (EORTC-QLQC30, median score 75). A pre-RC American Society of Anesthesiologists score > 2, active neoplasia, sexual inactivity, and stress urinary incontinence were associated with a worse QoL. After a multivariate analysis, sexual inactivity was the only independent factor related to an altered QoL. Conclusion: Patients with IONB reconstruction after RC have a high global QoL. Sexual activity could independently impact the global QoL, and it should be assessed pre- and post-operatively by urologists. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to report a multi-institutional retrospective case series of outcomes after robot-assisted laparoscopic pyeloplasty (RALP) in pediatric patients with complex pelvi-ureteric junction obstruction (PUJO). Methods: All patients undergoing complex RALP over the last 5 years were included. RALP was defined complex in the following cases of PUJO: anatomic variations including ectopic, malrotated, horseshoe, or duplex kidney and recurrent PUJO after failed open pyeloplasty. Results: Forty-eight patients underwent complex RALP in four European centers in the study period and included 18 girls and 30 boys with a median age of 8 years (range 5–12). The PUJO was associated with anatomic variations in 35/48 (72.9%), whereas a recurrent PUJO was present in 13/48 (27.1%). A dismembered Anderson–Hynes pyeloplasty was performed in all patients. The median operative time including docking was 178.5 min (range 117–255) and the median anastomotic time was 64.8 min (range 50–76). All patients were discharged on 2nd postoperative day (POD). The median follow-up was 18.2 months (range 14–43). The overall success rate was 95.8% (46/48). Early postoperative complications (< 30th POD) included urinary tract infections (UTIs) and stent-related irritative symptoms in 4/48 (8.3%) [II Clavien], whereas late complications (> 30th POD) included recurrence of PUJO in 2/48 (4.2%), who needed re-operation [IIIb Clavien]. Conclusions: RALP was safe, feasible, and with good mid-term outcome in complex PUJO. An accurate pre-operative planning, a standardized technique, and an experienced surgical robotic team represented key points to manage successfully such complex cases. [ABSTRACT FROM AUTHOR]

Purpose of Review: To highlight and review encouraging preliminary studies behind several alternative products and interventions for erectile dysfunction (ED). Recent Findings: Alternative treatments for ED are becoming more prevalent with increased consumer interest. "Natural" products are sold online, and numerous clinics offer various off-label and investigational interventions. These alternative treatments have demonstrated varying degrees of efficacy in randomized trials and meta-analyses, but none of these interventions has robust enough evidence to be considered first-line therapy. These treatments may find a role in combination with guideline treatments or may be used in novel penile rehabilitation research protocols. Summary: With growing interest in alternative treatment for men's health, an awareness of the literature is imperative for patient counsel. Alternative treatments, like l-arginine, have a growing body of evidence for efficacy in combination with PDE5i, and low-intensity shock wave therapy and stem cell therapy continue to demonstrate encouraging outcomes in ED trials.

Purpose: Open simple prostatectomy (OSP) is a standard surgical technique for patients with benign prostatic hyperplasia with prostate size larger than 80 ml. As a minimally invasive approach, robot-assisted simple prostatectomy (RASP) emerged as a feasible surgical alternative. Currently, there are no definite recommendations for the standard use of RASP. Therefore, we aimed at investigating various clinical outcomes comparing RASP with OSP. Methods: In this retrospective single-center study, we evaluated clinical data from 103 RASP and 31 OSP patients. Both cohorts were compared regarding different clinical characteristics with and without propensity score matching. To detect independent predictive factors for clinical outcomes, multivariate logistic regression analysis was performed. Results: Robot-assisted simple prostatectomy patients demonstrated a lower estimated blood loss and need for postoperative blood transfusions as well as less postoperative complications. OSP had a shorter operative time (125 min vs. 182 min) longer hospital stay (11 days vs. 9 days) and longer time to catheter removal (8 days vs. 6 days). In the multivariate analysis, RASP was identified as an independent predictor for longer operative time, lower estimated blood loss, shorter length of hospital stay, shorter time to catheter removal, less postoperative complications and blood transfusions. Conclusion: Robot-assisted simple prostatectomy is a safe alternative to OSP with less perioperative and postoperative morbidity. Whether OSP (shorter operative time) or RASP (shorter length of hospital stay) has a more favorable economic impact depends on the particular conditions of different health care systems. Further prospective comparative research is warranted to define the value of RASP in the current surgical management of benign prostatic hyperplasia. [ABSTRACT FROM AUTHOR]

Our objectives were to compare measurements of ureteral wall area, ureteral wall volume and ureteral wall thickness for their use in prediction of shock wave lithotripsy outcomes. We retrospectively identified 218 patients that underwent shock wave lithotripsy for ureteral calculi with pretreatment non-contrast computed tomography. We measured ureteral wall thickness, ureteral wall area and ureteral wall volume by high functional viewer. Ureteral wall thickness was defined as the maximum thickness of ureteral wall, and ureteral wall area as the area of ureteral wall around the stone in the maximal stone diameter on axial computed tomography image. Ureteral wall volume was defined as the volume of ureteral wall from the upper to lower edge of the stone. Treatment success was defined as absence of residual fragments within 3 months after the first session. We compared the outcome predictive power among these parameters and logistic regression analysis to identify factors contributing to treatment failure. The treatment success rate was 47.6%. Ureteral wall thickness, ureteral wall area and ureteral wall volume in successful cases were all significantly smaller than those in unsuccessful cases (all p < 0.01). Area under curve of ureteral wall volume was the largest of these parameters and significantly larger than that of ureteral wall thickness (p < 0.01). On multiple logistic regression analysis, ureteral wall volume was the only significant independent predictor of treatment outcome. Ureteral wall volume is a better predictor of shock wave lithotripsy outcome than ureteral wall thickness or ureteral wall area. [ABSTRACT FROM AUTHOR]

Purpose of Review: Radical cystectomy and urinary diversion remains the gold standard treatment for patients with high risk or muscle invasive bladder cancer. Despite the fact that a majority of patients are eligible for orthotopic neobladder, over 85% of patients receive incontinent urinary diversions, primarily over concerns for complications or postoperative voiding dysfunction. In this review, we explore the incidence, etiology, and treatment of voiding dysfunction after orthotopic neobladder creation in male and female patients. Recent Findings: Voiding dysfunction after orthotopic neobladder consists of urinary incontinence and urinary retention. Both are well-recognized potential sequelae, but occur more commonly in female patients. Recent studies have characterized voiding dysfunction as a dynamic problem that improves with time. While treatment options are limited, several techniques exist to minimize the risks of voiding dysfunction after orthotopic neobladder. Summary: Despite excellent functional outcomes in the majority of patients, concerns over voiding dysfunction after orthotopic neobladder may in part explain the disparity in receipt of incontinent versus continent urinary diversions. More prospective and patient-reported studies of voiding outcomes are required and newer more effective treatment options for voiding dysfunction are needed. [ABSTRACT FROM AUTHOR]

Purpose: This multicentric study aimed to report our experience with robot-assisted laparoscopic pyeloplasty (RALP) in children with horseshoe kidney (HSK). Methods: The records of 14 patients (11 boys and 3 girls with an average age of 9 years), who underwent RALP for repair of pelvi–ureteric junction obstruction (PUJO) in HSK in five international pediatric urology units over a 5-year period, were retrospectively reviewed. A dismembered pyeloplasty with no division of isthmus was performed in all the cases. Results: The average operative time including docking was 143.5 min (range 100–205). No conversions to laparoscopy or open surgery or intra-operative complications occurred. Patients were discharged on postoperative day 2 following catheter and drain removal. The JJ stent was removed at mean 33 days postoperatively. Overall success rate was 92.8%. As for postoperative complications, we recorded a urinary tract infection (UTI) and stent-related irritative symptoms, managed with medical therapy, in two patients (II Clavien) and an anastomotic stricture in one patient needing surgical revision with no further recurrence (IIIb Clavien). At follow-up, all the patients (one after redo-surgery) reported complete resolution of symptoms, improvement of hydronephrosis on ultrasound and no residual obstruction on diuretic renogram. Conclusions: Our experience suggested that RALP in HSK is safe, feasible and with good medium-term outcomes in expert hands. An accurate pre-operative planning associated with a standardized technique is key points to achieve good surgical and functional outcomes in these challenging cases. The da Vinci robot technology offers the advantages of MIS procedures and overcomes the technical challenges of laparoscopic approach. [ABSTRACT FROM AUTHOR]

Purpose: To compare the efficacy and safety of different treatment options for the management of proximal impacted ureteral stones (PIUS). Methods: A systematic literature search using Pubmed, Medline, Embase and Cochrane Library was conducted to obtain studies concerning different managements for PIUS up to Jan 2018. Summary odds ratios (ORs), standard mean differences (SMDs) or weighted mean differences with their 95% confidence intervals (CIs) were calculated to compare the efficacy and safety of all included treatment methods, registered in PROSPERO under number CRD42018092745. Results: A total of 15 comparative studies with 1780 patients were included. Meta-analyses of final stone-free rate (SFR) favored percutaneous nephrolithotomy (PCNL) over ureteroscopic lithotripsy (URL) (OR 10.35; 95% CI 5.26–20.35; P < 0.00001), laparoscopic ureterolithotomy over URL (OR 0.11; 95% CI 0.05–0.25; P < 0.00001) and URL over extracorporeal shockwave lithotripsy (OR 0.47; 95% CI 0.28–0.77; P = 0.003). As to complications, PCNL had a significantly higher blood transfusion rate (OR 7.47; 95% CI 1.3–42.85; P = 0.02) and a lower ureteral injury rate (OR 0.15; 95% CI 0.04–0.52; P = 0.003) compared with URL. It also shared a significantly lower stone-retropulsion rate (OR 0.03; 95% CI 0.01–0.15; P < 0.0001) and higher treatment costs (SMD = 2.71; 95% CI 0.71–4.70; P = 0.008) than URL. Conclusions: Our meta-analysis suggested that PCNL might be the best option for PIUS owing to its higher successful rate. Complications such as hemorrhage could be decreased by the application on mini-PCNL. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the clinical significance of ureteral wall thickness (UWT) for predicting spontaneous passage (SP) of uncomplicated ureteral stones of ≤ 10 mm. Methods: We retrospectively reviewed 418 patients with a diagnosis of uncomplicated ureteral stones who presented to Kori Hospital from 2011 to 2018. The maximum stone diameter and UWT at the stone site were measured from axial computed tomography images. Clinical predictors of 4-week SP were assessed using univariate and multivariate analyses. Receiver operating characteristic (ROC) curve analysis was applied to evaluate the accuracy of factors in predicting SP of ureteral stones. Results: Of the 418 patients, 202 (48.3%) spontaneously passed their stones within 4 weeks of their initial visit. Multivariate analysis showed that stone location, stone size, and UWT (odds ratio, 0.40; P < 0.001) were independent predictors of 4-week SP. ROC analysis showed that 2.71 mm was the optimal cut-off value for UWT, with a predictive accuracy of 0.83. Low UWT had a significantly higher 4-week SP rate than high UWT (76.4% vs. 14.7%, respectively; P < 0.001). In addition, high UWT was associated with a higher risk of stone-related complications within 4 weeks compared with low UWT (16.4% vs. 7.2%, respectively; P = 0.0044). Conclusions: UWT can serve as a potential predictive factor for 4-week SP and may help physicians to select patients who require immediate interventions among those with ≤ 10-mm ureteral stones.

Introduction: The pterygopalatine fossa (PPF) infiltration is performed to reduce blood flow during endoscopic sinus surgery and septorhinoplasty, as well as to control posterior epistaxis and provide regional anesthesia in dental procedures. PPF infiltration performed with consideration of the morphometrics of greater palatine foramen (GPF), greater palatine canal (GPC) and PPF would increase the success of the procedure and reduce the risk of complications. The aim of this study is to investigate the GPF, GPC, lesser palatine foramen (LPF), lesser palatine canal (LPC) and PPF morphology via the images obtained by CBCT, to provide information for interventional procedures. Materials and methods: GPF, GPC, LPF, LPC and PPF were morphometrically evaluated retrospectively in CBCT images of 75 female and 75 male cases by Planmeca Romexis program. The 19 parameters were measured on these images. Results: These parameters were evaluated statistically. The comparison of these parameters by genders revealed significant differences in distances between GPC–PC, PC–IOF, LPC–GPF, GPF–MS in the coronal and transverse planes, the distance between GPF and the occlusal plane of the teeth, GPF–PNS, GPF–IF and TD-GPF, and in the area of GPF. The number of LPF was found ranging from 1 to 5. Conclusion: Our results may help to insert to needle properly for application of maxillary nerve block with a high success rate and minimal complication. We recommend that the needle should be inserted 14–15 mm lateral to the midsagittal plane, 19–20 mm over the occlusal plane of the teeth and on the same line with the third molar teeth. For PPF infiltration through the GPF, the needle should be pushed forward 28 mm upward at 66° angle on the transverse plane and 14°–15° angle on the vertical plane. [ABSTRACT FROM AUTHOR]

Purpose: The question of whether orthotopic neobladder (ONB) reconstruction is superior to ileal conduit diversion (ICD) with respect to health-related quality of life (HRQoL) remains controversial. The goal of this study is to perform a meta-analysis to compare post-ICD and post-ONB HRQoL in patients with bladder cancer. Methods: A systematic search of Medline, Embase, the Cochrane Central Register of Controlled Trials, and the annual congress abstracts of the European Association of Urology (EAU), the American Urological Association (AUA) and the Société Internationale d'Urologie (SIU) up to June 2017 was conducted to identify all relevant clinical trials using validated questionnaires to assess HRQoL. A systematic review and meta-analysis were then performed. Results: A total of 2507 patients from 26 eligible studies were included. Meta-analyses showed significant differences favouring ONB patients in global health status (WMD + 9.13, p = 0.004), physical functioning (WMD + 11.57, p = 0.0001), role functioning (WMD + 9.64, p = 0.002), and social functioning (WMD + 6.81, p = 0.03) based on the EORTC-QLQ-C30 questionnaire and in the total score of FACT questionnaire (WMD + 6.80, p = 0.001). However, ONB patients were more likely to have postoperative urinary symptoms than ICD patients (WMD − 22.19, p = 0.0001). Conclusions: ONB patients are more likely to have a better global health status than ICD patients. Regardless of the type of urinary diversion (UD) surgery, a gradual improvement in HRQoL over preoperative status tended to stabilise after 12 months postoperatively. [ABSTRACT FROM AUTHOR]

Purpose: Horseshoe kidney is a rare congenital anomaly with potential clinical implications. The aim of this study was to determine the number of renal arteries and veins and the level at which the arteries branched off their parental vessels in individuals with horseshoe kidney (HSK) and in persons with separated kidneys (SK).Materials and methods: The analysis included computed tomography angiography studies of 331 patients (83 HSK and 248 SK). The number of renal vessels and diameters of renal arteries were determined, along with the level at which they branched in relation to other ramifications (four groups of origin were proposed) and their entrance of the vessels to the kidney.Results: Number of renal arteries in HSK group was 4.57 ± 1.39 per patient and 2.4 ± 0.43 in SK group (p < 0.0001). The distribution of branching level of renal arteries in HSK group was: I group ~ 57%, II group ~ 27%, III group ~ 15% and IV group < 1%, whereas in SK group the distribution was respectively: I group ~ 99%, II group < 1%, III and IV group − 0% (p = 0.0001). In HSK group, diameter of renal arteries branching above the IMA was 4.61 ± 1.58 mm, as compared with 3.96 ± 1.34 mm for the arteries branching below (p = 0.0004). Number of veins was 566 in SK group (87.70% of kidneys were supplied by single vein) and 323 in HSK group (9.64% kidneys were supplied by two veins) (p < 0.0001).Conclusion: In HSK group, renal arteries significantly more often branch off their parental vessels below the origin of IMA and such vessels are usually smaller.

Purpose: This study sought to compare perioperative outcomes and morbidities for open simple prostatectomy (OSP) and endoscopic green laser enucleation of the prostate (GreenLEP).Methods: In a single department, all consecutive patients who underwent OSP between January 2005 and December 2010 were retrospectively reviewed, and all consecutive patients undergoing GreenLEP between July 2013 and January 2017 were prospectively enrolled. Perioperative data, information regarding early postoperative complications for up to 6 months and outcomes were collected and retrospectively compared.Results: Overall, 204 patients were enrolled in each group. The baseline characteristics of patients in both groups were comparable. Intraoperative time was significantly longer for the OSP group than for the GreenLEP group (67 versus 60 min; p < 0.0001). The OSP group had significantly longer catheterisation (5 versus 2 days; p < 0.0001) and hospitalisation times (7 versus 2 days; p < 0.0001) than the GreenLEP group. The overall rate of complications was significantly higher after OSP than after GreenLEP (37.2 versus 20.6%; p = 0.0003); both Clavien-Dindo grade 3a complications (8.8 versus 0.98%) and Clavien-Dindo grade 3b complications (2.4 versus 3.4%) were observed. The transfusion rate was higher after OSP than after GreenLEP (8.3 versus 0.5%; p = 0.0001). The rehospitalisation rate was similar for both groups (7.8 versus 8.3%; p = 0.99).Conclusions: The results of this single-centre cohort study confirm those of similar prior investigations addressing endoscopic enucleation of the prostate. Compared with OSP, GreenLEP may have a more desirable perioperative profile with lower morbidity. In contrast, GreenLEP and OSP were associated with similar 6-month rehospitalisation rates.

Purpose: The only RCT available on complete bladder neck preservation (cBNP) during radical prostatectomy reported superior continence and QoL outcomes in the first 12 months after cBNP. We provide the first data on long-term urinary continence, QoL and biochemical recurrence (BCR) after complete bladder neck preservation in a randomised controlled cohort. Methods: After approval by IRB, 199 men recruited for the randomised, controlled single-blind Heidelberger cBNP Study had prostatectomy performed with (cBNP) or without (noBNP) complete bladder neck preservation. Only men with renewed consent for this follow-up were evaluated for continence, QoL outcomes and BCR by ICIQ-SF self-assessment questionnaire, Pad-use/day and PSA levels. Students-t test, Pearson's Chi-square, Fishers exact test and multiple logistic regression analyses were applied. Results: Mean follow-up was approx. 4 years. There were no significant differences in baseline characteristics between responders/non-responders or between study groups. We noted significantly higher continence rates (p = 0.004), less paduse (p < 0.001), reduced frequency (p = 0.023) and amount (p = 0.009) of urine loss, and higher QoL outcomes (p = 0.012) after cBNP. A younger age positively influenced continence (OR = 0.91), but the multivariate analysis found cBNP to be the only independent predictor of continence (p = 0.008; OR = 8.1). pT stage was the only predictor for positive surgical margins (PSM; p < 0.001). There was no significant difference in pT stage (p = 0.23) or BCR (p = 0.63) between study groups and also no significant correlation between BCR and presence (p = 0.26) or localisation (p = 0.11) of PSM, nerve sparing (p = 0.70), surgeon (p = 0.41), preoperative PSA (p = 0.53) or pT stage (p = 0.17). No cancer-related death was noted. Conclusions: Results of this first follow-up on a prospective randomised controlled cohort demonstrate that cBNP is associated with significantly higher continence and QoL outcomes without compromising cancer control making cBNP a novel objective during radical prostatectomy.

Purpose The greater and lesser palatine nerves and vessels supply the hard and soft palates, and the roots of these vessels and nerves run through a bony structure. However, the arrangement of blood vessels in the maxilla requires attention during clinical treatments, but detailed morphological information about changes in the greater and lesser palatine arteries and nerves during aging is unavailable. We therefore need detailed investigations of the morphology of the donor cadaver palatine using cone-beam computed tomography (CBCT) and macroscopic observations. Methods We investigated 72 donor cadavers using macroscopic segmentation and CBCT. The results' analysis examined differences in skull measurement parameters and differences between dentate and edentulous cases. Results The greater palatine artery and nerve showed different macroscopic arrangements in dentate and edentulous cadavers. We also classified three types of bony structures of the nerve and vessel roots in the molar regions of the palatine using CBCT images: the shallow groove, deep groove, and flat groove. The deep groove is the deepest of the three and is remarkable in edentulous elderly cadavers. Conclusion This study of macroscopic and CBCT data provides information useful for planning dental implant surgeries and autogenous bone harvesting. [ABSTRACT FROM AUTHOR]

Purpose: Anatomy of greater palatine foramen is important for maxillary nerve blocks, haemostatic procedures, and the treatment of neuralgia; although metrical data are available about its collocation, still several aspects need to be explored, such as the influence of the cranium size. Methods: The position of greater palatine foramen was assessed on 100 skulls through six measurements (distances from intermaxillary suture, posterior palatal border, posterior nasal spine, and incisive foramen; palatal length; relative position on palatal length) and two angles (angles at incisive foramen and greater palatine foramen). Maximum cranial length, maximum cranial breadth, cranial height and bizygomatic breadth, horizontal cephalic index, and Giardina Y-index were evaluated. Possible differences according to sex and side were assessed through two-way ANOVA ( p < 0.05). Measurements showing sexual dimorphism were further assessed through one-way ANCOVA including cranial parameters as covariates ( p < 0.05). Results: Distances of the greater palatine foramen from intermaxillary suture, incisive foramen, posterior palatal border, posterior nasal spine, palatal length, and position of the greater palatine foramen on the palatal length were statistically different according to sex ( p < 0.05), independently from general cranial dimensions but for the distance from the posterior palatal border. The angle at the incisive foramen and distances from intermaxillary suture and from posterior nasal spine showed statistically significant differences according to side ( p < 0.05). Conclusions: Results highlight that most of sexually dimorphic measurements useful for pinpointing the greater palatal foramen do not depend upon the cranium size. A more complete metrical assessment of the localization of the greater palatine foramen was provided. [ABSTRACT FROM AUTHOR]

Purpose: To analyze anatomical variations of the greater palatine canal (GPC) using cone beam computed tomography (CBCT) images. Methods: This study included 110 CBCTs. Axial slices were used to determine the shape of GPC and the number of lesser palatine foramina (LPF). Sagittal slices were used to assess the shape of the GPC and the number of lesser palatine canals (LPCs). Results: The most prevalent axial and sagittal GPC shapes were oval (46.36%) and hourglass (23.64%). Most GPCs presented one LPF (47.27%) and one LPC (90.91%). Conclusions: GPC anatomy is highly variable. CBCT is a useful tool for evaluating the anatomical variations of GPC. [ABSTRACT FROM AUTHOR]

Purpose of Review: The leading cause of voiding dysfunction in older men is benign prostatic obstruction. In the setting of a grossly enlarged prostate (>80cm), an open simple prostatectomy has been the gold standard for surgical treatment. Here, we will discuss the minimally invasive robot-assisted approach and compare it to the classic open approach and holmium laser enucleation of the prostate. Recent Findings: Literature on robot-assisted simple prostatectomy, in concurrence with our institutional experience, has shown an overall lower morbidity, shorter hospital stay, and decreased indwelling catheter time, with equivalent functional outcomes compared to open simple prostatectomy. Similar operative times and hospital stays were found compared to holmium laser enucleation of the prostate, although a steep learning curve and cost of new equipment hinder the wide spread use of this transurethral approach. Summary: On review of current literature in addition to our institutional experience, we favor robot-assisted simple prostatectomy over open simple, based on associated increased morbidity/catheter time/hospital stay, and holium laser enucleation of the prostate, based on steep learning curve and cost of new equipment.

Purpose: TUR-prostate (TUR-P) is considered the reference method for surgical treatment of benign prostatic obstruction (BPO); Greenlight laser photoselective vaporization (PVP) and thulium laser vapoenucleation (ThuVEP) have also been established as treatments of BPO. Objective of this prospective observation was to compare a large numbers of patients treated in everyday routine. Methods: This prospective multicentre data collection assesses morbidity and perioperative course of consecutive men treated with BPO-related transurethral surgery between 2011 and 2014 in a German metropolis area with TUR-P, PVP or ThuVEP. Results: Two thousand six hundred and forty-eight patients have been treated in the time period. All treatment options achieved immediate improvement of voiding parameters. Multivariate analyses proved shorter hospital stay after laser treatments as compared to resection ( p < 0.001). In terms of hospital stay, the advantage of ThuVEP compared to TUR-P increased with prostate volume ( p < 0.001). Patients with ongoing anticoagulation or bridging had prolonged hospital stay ( p < 0.001). Overall adverse events were least frequent in PVP ( p 0.016), as were Clavien 3b events ( p < 0.001). Conclusions: Surgical treatment of BPO is effective and safe independent of the surgical procedure. Volume reduction is most effective in ThuVEP; PVP has the lowest rate of severe complications. Laser treatment is associated with shorter hospital stay. Surgery under ongoing anticoagulation prolonged the post-operative hospital stay. [ABSTRACT FROM AUTHOR]

Objective: Investigation of the computerized dimensional anatomic location of the greater palatine foramen (GPF) and lesser palatine foramens (LPF) is important indicating site to collect palatal donor tissue, reconstructioning the orofacial area of the oncology patient and applying the greater palatine nerve block anesthesia. The aim of this study is to determine a patient-friendly landmark and to specify the precise location of the GPF in order to standardise certain anatomical marks of safe neurovascular bundle. Materials and methods: 120 bony palates were examined to detect the position of the GPF and the LPF related to adjacent anatomical landmarks using a computer software program. The GPF was assessed regarding the position, the diameter and the distances between each foramen and the midline maxillary suture (MMS), the inner border of alveolar ridge (AR), posterior palatal border (PBB), and incisive foramen (IF). Results: The GPF was identified as single in 81 %, double in 16 %, triple in 2 % and absent in 2 % of the specimens. The mean distances between the GPF and the MSS, the GPF and the AR, the GPF and the PPB, the GPF and the IF were 16, 4, 4, and 40 mm, respectively. In majority of the cases, the GPF was seen between the distal surfaces of the third maxillary molar (78 %). Single LPF was observed in 53.45 % of the skulls, two LPF were observed in 31 % of the skulls bilaterally and five LPF were rare in 2.1 % of the specimens. The LPF was most commonly at the junction of the palatine bone and the inner lamella of the pterygoid plate (71.9 %). Conclusions: This study made possible to investigate the variability of the GPF and the feasibility of the greater palatine neurovascular bundle, and to calculate the lengths of some parameters with the help of certain software. To collect the donor tissue of the neurovascular greater palatine network, each distance among the AR-GPF-PPB were equal to 4 mm. To estimate the possible length of the graft, the incision was made along the third and the second molar to the IF as 4 cm. The data we obtained within this study have been presented to help the surgeons avoid unexpected hemorrhage during the palatinal procedures such as posttraumatic dental reconstruction, maxillofacial tumor resections, palatal micro-implants, and dentofacial orthopedic surgery.

Purpose: To evaluate the efficacy and safety of transurethral enucleation of the prostate (TUEP) versus transvesical open prostatectomy (OP) for the management of large benign prostatic hyperplasia (BPH). Methods: Randomized controlled trials (RCTs) comparing TUEP and OP were identified from PubMed, Embase and Web of Science up to February 28, 2015. A meta-analysis was conducted with the STATA 12.0 software. Results: Nine RCTs including 758 patients were enrolled in our meta-analysis. There were no significant differences between the two groups in the maximum urinary flow rate at 1, 3, 6 months, 1 and 2 years: postvoiding residual urinary volume, prostate-specific antigen, international prostate symptom score and quality of life score at 1, 3, 6 months and 1 year; or international index of erectile function at 3, 6 months and 1 year. Perioperative outcomes including hemoglobin level drop, catheter period, irrigation length and hospital stay favored TUEP, while operative time and resected prostate weight favored OP. There was significantly less blood transfusion with TUEP, but no significant differences were found in other complications such as recatheterization, urinary tract infection, reintervention for clots and bleeding control, incidence of pneumonia and infarction, transient incontinence, bladder neck contracture, urethral stricture and recurrent adenoma. Conclusions: TUEP can be performed effectively and safely with functional outcomes and complications similar to OP for large BPH, whereas it has the advantages of a shorter catheter period, shorter hospital stays and less blood transfusion. These findings seem to support TUEP as the next-generation 'gold standard' of surgery for large BPH. [ABSTRACT FROM AUTHOR]

The definitive treatment for symptomatic large volume (>80 mL) benign prostatic hyperplasia (BPH) is simple prostatectomy (SP). This can be performed by utilizing a retropubic, suprapubic, or a combined approach. The latter two approaches allow for the management of concomitant bladder diverticulum or stones through the same incision. Each approach affords unique technical strengths and weaknesses that must be considered in light of patient characteristics and concomitant pathology. SP allows for removal of the entire prostatic adenoma while obviating some of the neurovascular and continence issues that can arise from radical prostatectomy. Concerns with SP include its relatively high perioperative morbidity, notably bleeding. Therefore, there is increasing interest in less invasive options, including enucleation procedures and minimally invasive SP. This review presents an update regarding trends and outcomes of SP, as well as the effectiveness and popularity of alternative treatments. [ABSTRACT FROM AUTHOR]

The pancake kidney (PK) is a rare type of renal anomaly in which both kidneys completely fuse without an isthmus. In the previous reports, PKs have double ureters and are located in the pelvic cavity. We encountered a rare case of PK with a single ureter, which is located in the left retroperitoneal space, in a 95-year-old female cadaver, which was detected during a dissection course. In our case, the major calyces joined to form a single renal pelvis, which continued as a single ureter. To the best of our knowledge, this is the first report on PK with a single ureter that is located not in the pelvic cavity but in the retroperitoneal space. The knowledge of such anomalous presentation is important to avoid any complications during retroperitoneal surgery. [ABSTRACT FROM AUTHOR]

Purpose: To analyze greater palatine canal (GPC) dimensions using cone-beam computed tomography (CBCT) images, and to evaluate the position of the greater palatine foramen (GPF) with respect to various landmarks selected in relation to dental status. Methods: This study included 150 CBCTs. Axial slices were used to determine the position and dimensions of the GPF. Sagittal slices were used to assess GPC length. Reference lines were established to evaluate the GPC diameter in sagittal and coronal slices. Results: From the 77 GPF analyzed, 76 were located on level 2. Average posterior GPF distance was 6.59 ± 3.27 mm on right side and 7.35 ± 3.40 mm on left side. Several measurements to determine the position and dimensions of the GPF presented significant values ( p ≤ 0.05). GPC length was 12.31 ± 1.96 mm on right side and 12.52 ± 2.15 mm on left side, statistically significant differences were detected between genders only on right canal ( p ≤ 0.004). Sagittal and coronal reference lines presented significantly higher values for men except for the S3 ( p < 0.062) and C1 ( p < 0.067) in the left GPC. Conclusions: CBCT is a useful tool for evaluating GPC morphometrically in the three anatomical slices. The sagittal nasal plane and posterior nasal plane are two intraoral anatomical landmarks for the location of the GPF. Their scant variability allows accurate identification of GPFs in both dentate as well as edentulous patients. [ABSTRACT FROM AUTHOR]

Background: Various surgical interventions including esthetic surgery, salivary gland excision, and open reduction of fracture have been performed in the area around the mandibular angle and condyle. This study aimed to comprehensively review the anatomy of the neurovascular structures on the angle and condyle with recent anatomic and clinical research. Methods and results: We provide detailed information about the branching and distributing patterns of the neurovascular structures at the mandibular angle and condyle, with reported data of measurements and proportions from previous anatomical and clinical research. Our report should serve to help practitioners gain a better understanding of the area in order or reduce potential complications during local procedures. Reckless manipulation during mandibular angle reduction could mutilate arterial branches, not only from the facial artery, but also from the external carotid artery. The transverse facial artery and superficial temporal artery could be damaged during approach and incision in the condylar area. The marginal mandibular branch of the facial nerve can be easily damaged during submandibular gland excision or facial rejuvenation treatment. The main trunk of the facial nerve and its upper and lower distinct divisions have been damaged during parotidectomy, rhytidectomy, and open reductions of condylar fractures. Conclusion: By revisiting the information in the present study, surgeons will be able to more accurately prevent procedure-related complications, such as iatrogenic vascular accidents on the mandibular angle and condyle, complete and partial facial palsy, gustatory sweating (Frey syndrome), and traumatic neuroma after parotidectomy.

Purpose: To investigate feasibility, safety, and efficacy of salvage radical prostatectomy (RP) for recurrent prostate cancer (PCa) after focal treatment with TOOKAD Soluble vascular-targeted photodynamic therapy (VTP). Methods: Nineteen patients underwent RP after biopsy-proven PCa post-focal VTP. We reported: operation time, blood loss, transfusion, complications, urethral catheterization time, functional outcomes, and short-term oncologic outcomes. Results: Median age was 64 years (58-70). Median PSA before VTP was 6.30 ng/ml (3.20-9.80). Median delay between VTP and RP was 17 months (8-48). Median blood loss was 400 ml (100-1,000). Median operation time was 150 min (90-210), median urethral catheterization time was 7 days (5-18), and median hospital stay was 7 days (4-21). There was no perioperative mortality. Three patients had related per-operative complications: one pelvic hematoma (150 cc) (Clavien IIIa), one per-operative transfusion (900 cc hemorrhage) (Clavien II), and one superficial wound infection (Clavien I). After a median follow-up of 10 months (1-46), 13 were completely continent (68 %), five needed ≤1 pad/day, and one needed 3 pads/day (Clavien I). Severe erectile dysfunction was observed before and after RP (respectively 8 and 18). Ten patients regained potency with appropriate treatment. Median postoperative PSA was 0.02 ng/ml (<0.01-0.38) and remained undetectable for 16 patients (84 %). Nine patients had positive margins and six underwent complementary radiotherapy. Positive margins were significantly associated with bilateral VTP [risk ratio = 4.3, 95 % confidence interval (1.6-11.7), p = 0.003]. Conclusion: Salvage RP after VTP treatment was feasible, safe, and efficient to treat most of the locally recurrent PCa. Short-term oncologic and functional outcomes were promising, but further studies are required. [ABSTRACT FROM AUTHOR]

The aim of the study was to determine the possible predictive value of certain patient- and stone-related factors on the stone-free rates and auxiliary procedures after extracorporeal shock wave lithotripsy in patients with impacted proximal ureteral calculi. A total of 111 patients (86 male, 25 females M/F: 3.44/1) with impacted proximal ureteral stones treated with shock wave lithotripsy were evaluated. Cases were retrieved from a departmental shock wave lithotripsy database. Variables analyzed included BMI of the case, diameter of proximal ureter and renal pelvis, stone size and Hounsfield unit, ureteral wall thickness at the impacted stone site. Stone-free status on follow-up imaging at 3 months was considered a successful outcome. All patients had a single impacted proximal ureteral stone. While the mean age of the cases was 46 ± 13 years (range 26-79 years), mean stone size was 8.95 mm (5.3-15.1 mm). Following shock wave lithotripsy although 87 patients (78.4 %) were completely stone-free at 3-month follow-up visit, 24 (21.6 %) cases had residual fragments requiring further repeat procedures. Prediction of the final outcome of SWL in patients with impacted proximal ureteral stones is a challenging issue and our data did clearly indicate a highly significant relationship between ureteral wall thickness and the success rates of shock wave lithotripsy particularly in cases requiring additional procedures. Of all the evaluated stone- and patient-related factors, only ureteral wall thickness at the impacted stone site independently predicted shock wave lithotripsy success. [ABSTRACT FROM AUTHOR]
