- Abstract
Background: Urgent laparoscopic cholecystectomy has been established as the best treatment for acute cholecystitis. However, conservative treatment is advocated for high-risk patients. Failure of conservative treatment can result in high-risk operations with relatively high rates of operative morbidity. Percutaneous cholecystostomy is a good option for these patients. Recently, percutaneous aspiration of the gall bladder without drain has been described., Methods: A protocol of initial conservative management in high-operative-risk patients admitted with acute cholecystitis was prospectively assessed. Patients who did not respond to antibiotics were treated with percutaneous trans-hepatic aspiration of the gall bladder under ultrasound guidance. Following discharge, the patients were seen in the outpatient clinic and elective laparoscopic cholecystectomy was considered and scheduled as necessary., Results: Between January 2011 and December 2012, 33 patients with persistent clinical and sonographic signs of acute cholecystitis after failure of initial antibiotic treatment underwent gall bladder aspiration under ultrasound guidance. No complications related to the procedure were reported. In 25 patients (76 %), the procedure was successful and they were discharged. Seven patients needed repeated aspiration. Eight patients (24 %) who did not improve underwent percutaneous cholecystostomy and were discharged with a drain and later reevaluated for elective surgery. The mean hospital stay of patients with successful aspiration was 3 days. During the follow-up period, 23 patients underwent elective interval laparoscopic cholecystectomy. Two were converted to open surgery (8.7 %)., Conclusions: Conservative treatment and delayed operation is an acceptable option for acute cholecystitis. Percutaneous gall bladder aspiration is a simple and effective procedure, with a high success rate and low morbidity. Laparoscopic cholecystectomy after drainage of the gall bladder has low morbidity with a relatively low conversion rate.

- Abstract
Purpose: To define the time needed by urology residents to attain proficiency in computer-aided robotic surgery to aid in the refinement of a robotic surgery simulation curriculum., Methods: We undertook a retrospective review of robotic skills training data acquired during January 2012 to December 2014 from junior (postgraduate year [PGY] 2-3) and senior (PGY4-5) urology residents using the da Vinci Skills Simulator. We determined the number of training sessions attended and the level of proficiency achieved by junior and senior residents in attempting 11 basic or 6 advanced tasks, respectively., Results: Junior residents successfully completed 9.9 ± 1.8 tasks, with 62.5% completing all 11 basic tasks. The maximal cumulative success rate of junior residents completing basic tasks was 89.8%, which was achieved within 7.0 ± 1.5 hours of training. Of senior residents, 75% successfully completed all six advanced tasks. Senior residents attended 6.3 ± 3.5 hours of training during which 5.1 ± 1.6 tasks were completed. The maximal cumulative success rate of senior residents completing advanced tasks was 85.4%., Conclusion: When designing and implementing an effective robotic surgical training curriculum, an allocation of 10 hours of training may be optimal to allow junior and senior residents to achieve an acceptable level of surgical proficiency in basic and advanced robotic surgical skills, respectively. These data help guide the design and scheduling of a residents training curriculum within the time constraints of a resident's workload.

- Abstract
Introduction: Urologic malignancies are often diagnosed at an older age, and are increasingly managed utilizing robotic-assisted surgical techniques. As such, we assessed and compared peri-postoperative complication rates following robotic urologic surgery in elderly and younger patients., Materials and Methods: A retrospective analysis of IRB-approved databases and electronic medical records identified patients who underwent robotic-assisted urologic surgery between December 2003-September 2013. Patients were grouped according to surgical procedure (partial nephrectomy, radical cystectomy, radical prostatectomy) and age at surgery (≤ 74 or ≥ 75 years old). Associations between age, comorbidities, Charlson comorbidity index (CCI), and patient outcomes were evaluated within each surgery type., Results: 97.5% and 2.5% of patients were ≤ 74 or ≥ 75 years old, respectively. Cystectomies, partial nephrectomies and prostatectomies accounted for 3.5%, 9.5% and 87.1% of surgeries, respectively. Within cystectomy, nephrectomy and prostatectomy groups, 24.4%, 12.5% and 0.6% patients were ≥ 75 years old. Within each surgical type, elderly patients had significantly elevated CCI scores. Length of stay was significantly prolonged in elderly patients undergoing partial nephrectomy or prostatectomy. In elderly cystectomy, partial nephrectomy and prostatectomy patients, 36.7%, 14.3% and 5.9% suffered ≥ 1 Clavien grade 3-5 complication, respectively. Major complications were not significantly different between age groups. A qualitatively similar pattern was observed regarding Clavien grade 1-2 complications., Conclusions: The risks of robotic-assisted urologic surgery in elderly patients are not significantly elevated compared to younger patients.

- Abstract
Introduction: Renal masses are commonly managed by partial nephrectomy (PN) or active surveillance (AS). We assessed the impact of patient demographics and clinical indices in determining treatment decisions of renal masses between these two options., Materials and Methods: We retrospectively reviewed our renal mass database to retrieve demographic and clinical records of patients who underwent immediate PN or entered a >= 12 month period of AS during February 1999 to May 2014. Age, gender, body mass index (BMI), Charlson Comorbidity Index (CCI) score, follow up time, tumor size, tumor location, renal invasion, creatinine, and estimated glomerular filtration rate (eGFR) were assessed as predictors of the selected treatment option., Results: Seven hundred thirty-five patients with 744 renal masses underwent immediate PN, while 123 patients with 140 renal masses entered active surveillance. PN patients were predominantly male, younger, had elevated BMI, lower CCI scores, elevated eGFR and had larger tumors that invaded further into the renal collecting system. Renal masses in men were more likely to be treated by PN, while patients categorized as overweight or obese were 2-3 fold more likely to have their renal mass being manage by PN (versus patients with BMI in the normal range). Higher CCI scores were associated with a renal mass being more likely to be treated by AS, while increased renal mass size was associated with decisions to treat with PN. Compared to cortical location, renal masses abutting the renal collecting system were more likely to be treated by PN., Conclusions: Gender, BMI, CCI, tumor size, and tumor invasion into the renal system are useful predictors of renal mass treatment.

- Abstract
Aims: To determine the growth rate of renal masses (RMs) under active surveillance (AS), and to describe the clinical outcome of AS patients., Materials and Methods: We conducted a retrospective review of an AS database to obtain demographics, radiological and pathologic characteristics and RM size of patients. RMs were followed at 6-12 month intervals for ≥1 year with computed tomography (CT), magnetic resonance imaging (MRI), or renal ultrasound. Kaplan-Meier analysis determined the annual likelihood of intervention. RMs were divided into 3 radiographic subcategories (solid, cystic, and angiomyolipoma). A linear regression model determined RM growth rates., Results: 131 RMs in 114 patients were included. Median age, Charlson Comorbidity Index score and mean follow-up were 69.1 years, 4.0 and 4.2±2.6 years, respectively. Maximal tumor diameter (MTD) at diagnosis was 2.1 ± 1.3 cm. 49 RMs exhibited negative or zero net growth. Mean MTD growth rate for all RMs was 0.72±3.2 (95% CI: 0.16-1.28) mm/year. When stratified by MTD at diagnosis, mean RM growth rates were 0.84, 0.84, 0.44, 0.74 and 0.71 mm/year for RMs ≤1 cm, 1-≤2cm, 2-≤ 3cm, 3-≤ 4cm and ≥4cm, respectively (p≤0.01). The 5 and 10-year freedom from intervention rates were 93.1% and 88.5%, respectively. There was a single case of suspected metastases, but no deaths related to kidney cancer., Conclusions: RMs under AS grew slowly, and had a low incidence of requiring surgical intervention and progression. Solid enhancing masses grew slowly, and were more likely to trigger intervention. AS should be considered for selected patients with small RMs.

- Abstract
Objectives: We sought to identify preoperative patient and tumor characteristics that may be useful prognostic indicators of postsurgical outcome in patients undergoing laparoscopic adrenalectomy (LA)., Subjects and Methods: Data from 92 patients who underwent 93 transabdominal LA procedures between 2006-2012 were retrieved. Patients were stratified based on estimated blood loss (EBL), length of stay (LOS), and perioperative complications. Interdependencies between surgical outcome and patient demographics, tumor characteristics, comorbidities, and Charlson Comorbidity Index (CCI) were statistically analyzed. The predictive capacity of each index was assessed using receiver operating characteristic curves., Results: Neither age, gender, tumor laterality, body mass index, American Society of Anesthesiologists (ASA) score, nor CCI predicted the occurrence of perioperative complications. EBL was significantly associated with increased age, tumor size, ASA score, and CCI, whereas prolonged LOS was associated with higher ASA score. Tumor size was related, although not significantly, to LOS and perioperative complications. Tumors ≥7.5 cm in diameter were significantly associated with worse perioperative outcomes., Conclusions: LA for adrenal lesions demonstrated reasonable complication rates and perioperative outcomes. Tumor size, CCI, and ASA score are predictive of increased EBL and LOS.

- Abstract
Introduction: This article reports outcomes of 2 patients who received a single-stage renal transplantation and concomitant urinary-diversion procedure., Technical Considerations: We followed the clinical diagnosis and outcome of 2 patients who underwent renal transplantation and urinary diversion as a single-stage procedure by retrospectively reviewing a Hartford Hospital Institutional Review Board-approved kidney database. Patient demographics, renal function, and surgical outcomes were examined., Conclusion: Two patients underwent a simultaneous renal transplantation-ileal conduit creation to surgically manage their end-stage renal disease. One patient did not have any surgical complications, whereas the other suffered from a postoperative ileus (Clavien grade 3a), atrial fibrillation (Clavien grade 2), hypertension (Clavien grade 2), methicillin-resistant Staphylococcus aureus at the incisional site (Clavien grade 2), and a positive urine culture managed using antibiotics (Clavien grade 2). No major complications were observed and both have favorable outcomes at 23 and 19 months after surgery, respectively. This report demonstrates the feasibility and safety of single-stage renal transplantation and urinary diversion in select patients with end-stage renal disease status after cystectomy. To our knowledge, this is the first report of this novel technique., (Copyright © 2014 Elsevier Inc. All rights reserved.)

- Abstract
Background and Purpose: Obese patients undergoing surgical procedures are at increased risk for perioperative morbidity. The purpose of this study is to determine whether there is an association with body mass index (BMI), clinicopathologic features, and perioperative outcomes and complications in patients undergoing robot-assisted laparoscopic partial nephrectomy (RPN)., Patients and Methods: Medical records of 283 patients who underwent RPN between 2007 and 2012 were reviewed from an Institutional Review Board approved database. We analyzed the association of perioperative outcomes and complications of the surgery with BMI and clinicopathologic features using analysis of variance, Kruskal-Wallis test, t test and chi-square-test. Eventually, independent factors associated with perioperative outcomes and complications were studied using univariate and multivariate regression analysis., Results: Perioperative outcomes including estimated blood loss (EBL), length of hospital stay (LOS) and operative time (OT) were significantly associated with BMI (P=0.002, P=0.009 and P=0.002, respectively). Warm ischemia time (WIT), perioperative complications, and change in glomerular filtration rate (GFR) before and after surgery were not associated with BMI (P=0.459, P=0.86 and P=0.773). In multivariate analysis, BMI, tumor size≥4 cm, and collecting system invasion were independently associated with EBL and OT. Increased LOS was independently associated with BMI and tumor size ≥4 cm., Conclusions: Increasing BMI was not associated with a significant increase in perioperative complications, WIT, or change in GFR in patients undergoing RPN at a high-volume tertiary medical center. Collecting system invasion or tumor size ≥4 cm and BMI were independently associated with higher EBL, LOS, and OT, however.

- Abstract
Reconstructive techniques performed using open, laparoscopic, or hand-assisted techniques depend on the surgeon's ability to approximate tissues and secure bleeding vessels safely and efficiently. The indications for hand-assisted suturing include hemostasis, diaphragmatic and visceral repair, and reconstruction. The equipment required includes a standard laparoscopic needle driver, sutures with noncutting needles, and the handaccess device. The surgeon should be comfortable with the particular equipment available in his/her operating room. Techniques for suturing during hand-assisted laparoscopic reconstructive surgery are described.

- Abstract
Purpose: Hand assisted laparoscopy combines aspects of open and laparoscopic surgery. A hand in the abdomen may facilitate laparoscopic live donor nephrectomy, allowing more urologists to participate. We report and compare our initial series of hand assisted laparoscopy donor nephrectomy with nephrectomy performed by standard open methods., Materials and Methods: In the last 18 months 60 patients at 2 institutions underwent hand assisted laparoscopy donor nephrectomy. This cohort was compared to a contemporary group of 31 patients who underwent open donor nephrectomy via a flank incision at our 2 institutions. Demographic and outcome data were compared retrospectively in a nonrandomized fashion in the 2 groups., Results: Demographic data on patient age, male-to-female ratio and body mass index were similar in the 2 groups. Operative time, transfusion rate, time to oral intake and complications were also similar. However, estimated blood loss, change in hematocrit preoperatively to postoperatively, hospitalization, parenteral and oral narcotic requirement, and donor convalescence were significantly less in the hand assisted laparoscopy versus open groups. In terms of allograft function, nadir creatinine, time to nadir creatinine, creatinine clearance at 6, 12, and 18 months, delayed graft function, episodes of acute rejection and ureteral stricture were similar in the groups., Conclusions: Hand assisted laparoscopy is safe, efficacious and reproducible for living related donor nephrectomy. Compared with the open technique hand assisted laparoscopy provides the donor with significantly decreased postoperative morbidity, while enabling excellent allograft function. Further randomized prospective studies are warranted.

- Abstract
Background and Purpose: For patients with upper tract transitional-cell carcinoma (TCC), nephroureterectomy with removal of a bladder cuff is the standard of care. Historically, it has been performed using two incisions or one large incision extending from the lateral flank to the symphysis pubis. We describe an alternative using endoscopic management of the bladder cuff combined with hand-assisted laparoscopic (HAL) nephroureterectomy. We compared our results using these minimally invasive advances with those of a contemporary open nephroureterectomy series., Patients and Methods: Between May 1998 and June 1999, we performed 11 HAL nephroureterectomies with endoscopic management of the bladder cuff for the treatment of upper tract TCC. The results were compared with those in a contemporary series of 11 patients undergoing the traditional open operation at our institution. The patient age, male:female ratio, and ASA classification were similar in the two groups. Intraoperative measures considered were operative time, estimated blood loss, need for transfusion, complications, specimen weight and volume, pathologic stage and grade of the tumor, and the status of the surgical margins. Postoperative endpoints were time to sustained fluid intake; epidural, parenteral, and oral narcotic requirements; length of stay; and complications. Follow-up, specifically disease recurrence and overall survival, was recorded., Results: The mean operative time was 291 minutes for HAL v 232 minutes for the open operation (P = NS). The average blood loss was 144 v 311 mL (P = 0.04), the mean specimen weight 368 v 392 g (P = NS), and the mean specimen volume was 630 v 693 cc (P = NS). No patient in the HAL group had a positive surgical margin, but one patient in the open surgery group did. The time to sustained fluid intake postoperatively averaged 1.4 v 2.3 days for the HAL and open groups, respectively (P = NS). The epidural narcotic requirement was 0 v 2.7 days (P < 0.001), the mean parenteral narcotic requirement was 45 v 44 mg of morphine sulfate equivalent (P = NS), and the oral narcotic requirement was 5.8 v 16 tablets (P < 0.04). The average length of stay was 4.6 days for the HAL group v 6.1 days for the open group (P = 0.04). In both groups, 7 of the 11 patients (63%) were without evidence of disease with a mean follow-up of 13 (HAL) and 17 (open) months., Conclusions: Hand-assisted laparoscopic nephroureterectomy with endoscopic management of the bladder cuff is an efficacious alternative to open surgery. The operative time, specimen weight and size, and risk of recurrence for the two procedures are similar. However, convalescence, as measured by pain medication requirements and length of stay, is significantly better with laparoscopy. Longer follow-up with larger numbers of patients is in progress.

Stifelman MD, Sosa RE, and Shichman SJ
- Abstract
Hand-assisted laparoscopy (HAL) allows surgeons direct hand contact with the operative field, maximizing tactile feedback and minimizing surgical injury to the patient. Indications for HAL include radical, donor, and partial nephrectomies, nephroureterectomy, and, most recently, dismembered pyeloplasties. The advantages of HAL surgical techniques in comparative experience with standard laparoscopic technique are described.

- Abstract
Background and Purpose: The indications for partial nephrectomy are expanding as newer and more complete data come forth. A partial nephrectomy has traditionally required a generous flank incision. We report our experience using hand-assisted laparoscopy (HAL) as a less-invasive approach to partial nephrectomies., Patients and Methods: Between October 1999 and May 2000, we performed 11 HAL partial nephrectomies. The average age of the patients was 55.7 years, the average body mass index was 25.6, and the average ASA class was 2.2. The indications for partial nephrectomy were enhancing solid renal lesions (N = 9) and nonfunctioning renal moiety in a duplicated system (N = 2). In the majority of cases, access to the renal pedicle was obtained prior to the partial nephrectomy. However, in no case did the renal artery or vein require occlusion. Several excisional techniques were employed, but all relied heavily on the Harmonic Scalpel in conjunction with the argon beam coagulator. Different hemostatic agents were applied to the renal defect, including Surgicel, Avitene, and fibrin-soaked Gelfoam activated by thrombin. In several instances, pledget reinforced sutures were placed in the renal capsule to aid with hemostasis., Results: The average operative time was 273 minutes, the estimated blood loss 319 mL, and the change in hematocrit 7.3 points. No patient required a transfusion, and there was one conversion to open. Postoperatively patients, required an average of 35.6 mg of morphine sulfate equivalent and 8.2 narcotic tablets, resumed oral intake in 1.7 days, and were discharged home in 3.3 days. There were no major complications and only two minor complications. Postoperatively, five lesions were found to be benign, four lesions were confirmed to be malignant, and two lesions were consistent with a nonfunctioning duplicated renal moiety. Specimen size averaged 180 cc, and the tumor diameter averaged 1.9 cm. There were no positive surgical margins., Conclusions: Hand-assisted laparoscopic partial nephrectomy is feasible and reproducible. The surgeon's hand in the operative field facilitates dissection, vascular control, hemostasis, and suturing. Further long-term and prospective studies are underway.

- Abstract
Chronic inflammation or prior surgical procedures may complicate the laparoscopic performance of simple nephrectomy. In these difficult cases, hand-assisted laparoscopy may be useful. The position of the hand port depends on the particular situation, but the port must allow flexion of the wrist and access to the entire surgical field. The hand-assisted procedure is similar to standard laparoscopy in analgesic use, time to oral intake, length of stay, and time to full recovery. Hand-assisted laparoscopy allows the inexperienced surgeon to perform laparoscopy with the aid of tactile sensation and three-dimensional spatial orientation. For the experienced surgeon, the technique offers an alternative to open conversion when the laparoscopic procedure fails to progress.

- Abstract
Hand-assisted laparoscopic surgery has been used to perform nephrectomies. This report contrasts the efficacy, postoperative morbidity, length of stay, analgesic use, and time to recovery for hand-assisted laparoscopic nephrectomy, to standard laparoscopic and open nephrectomy. The technique for hand-assisted laparoscopic nephrectomy used at two institutions is described. The results from these two institutions are contrasted to results in the literature for standard laparoscopic and open nephrectomy. Standard and hand-assisted laparoscopic nephrectomy seem similar in terms of efficacy of surgery, time of surgery, estimated blood loss, length of stay, and time to full recovery. The two laparoscopic techniques seem to show advantage over open surgery in respect to shorter hospital stay, faster full recovery, and less analgesic use. The operative time for the laparoscopic surgeries is longer than the open surgery operating time. Hand-assisted laparoscopic surgery seems to be equivalent to standard laparoscopy. As urologists around the world are trained in hand-assisted laparoscopic nephrectomy, a more refined look at these early results will be possible., (Copyright 2000 by W.B. Saunders Company)

- Abstract
Several laparoscopic approaches to the adrenal gland have been described. The lateral transperitoneal approach has several distinct advantages when contrasted with other techniques for laparoscopic adrenalectomy (LA). We present our technique and results obtained in 50 consecutive transperitoneal LAs. We review 50 consecutive laparoscopic adrenalectomies (28 female, 19 male) performed from 1993 to 1998 S.J. Shichman or R.E. Sosa was either the primary surgeon or the first assistant for all cases. The lateral transperitoneal approach described below was used in all cases. Indications for adrenalectomy included Cushing's syndrome (13), aldosteronoma (15), pheochromocytoma (7), nonfunctioning adenoma (11), hyperplasia (2), and 1 case each of Carney's syndrome and metastasis to the adrenal gland. We performed 5 bilateral, 22 left, and 18 right laparoscopic adrenalectomies. The average time needed for bilateral adrenalectomy was 503 min (range 298-690 min); for left adrenalectomy, 227 min (range 121-337 min); and for right LA, 210 min (range 135-355 min). We demonstrated a yearly trend in lower operative times. The largest adrenal gland removed measured 13.8 x 6.7 x 3.5 cm. Intraoperative blood loss was low. Only one patient received a blood transfusion. Conversion to open adrenalectomy was not required. Postoperative analgesic requirements were low. The average length of stay was 3.8 days for bilateral LA and 3 days for unilateral LA. Complications occurred in 5 patients (2 wound infections, 2 hematomas, and 1 pleural effusion). There was no mortality. Lateral transperitoneal adrenalectomy is a safe and efficient technique for the removal of functional and nonfunctional adrenal masses. This technique is associated with low morbidity, a minimal postoperative analgesic requirement, and a short hospital stay and, in our opinion, is more versatile than the retroperitoneal approach.

- Abstract
Purpose: We report our experience with bilateral laparoscopic adrenalectomy for total adrenal ablation in patients with Cushing's syndrome., Materials and Methods: Four women (mean age 63 years) with Cushing's syndrome secondary to nonlocalized ectopic adrenocorticotropic hormone production in 3 and pituitary microadenoma after failed transsphenoidal ablation in 1 underwent bilateral transabdominal laparoscopic adrenalectomy. Preoperatively risk was III or IV according to the American Society of Anesthesiologists classification., Results: In all cases bilateral laparoscopic adrenalectomy was successfully performed. Operative time ranged from 375 to 475 minutes (mean 404) and mean blood loss was 162 cc. All patients resumed oral intake on postoperative day 1, mean number of postoperative parentral narcotic doses was 2.25 and mean postoperative hospital stay was 5.75 days (range 3 to 8). Complications included an abdominal wall hematoma. All patients resumed baseline activity by postoperative day 14., Conclusions: Our experience in 4 cases of Cushing's syndrome suggests that bilateral laparoscopic adrenalectomy is a safe and effective alternative to open adrenalectomy. Further experience with this technique will likely decrease operative time, and confirm the benefit of a decreased hospital stay and convalescence.

- Abstract
More and more laparoscopic procedures are performed in Urology each day. Attempts at reducing the invasiveness of conventional surgical procedures and the possibility of permitting patients to resume their activities earlier have considerably extended the indications for laparoscopy. Laparoscopic access to the urinary system is not simple since it is almost completely located in the retroperitoneal region and peritoneal insufflation with CO2 puts organs that were previously protected within the abdominal cavity at risk. The urologist must operate in a surgical field that was previously unfamiliar to him, with no stereoscopic vision and using instruments without all of the functions of those of conventional surgery. The complications of laparoscopic surgery may present intraoperatively or late postoperatively. Correct patient selection and preparation can prevent many of the complications that arise during trocar insertion. The physiological response to peritoneal insufflation with CO2 must be well understood if the possible complications arising from pneumoperitoneum are to be prevented or correctly treated. The different complications of laparoscopic surgery in Urology are described. The potential problems of the different stages of the procedure, the pathophysiological aspects, prevention and treatment are discussed.

- Abstract
Depressed and nondepressed Ss were exposed to either inescapable noise or no noise conditions in an attempt to replicate a typical learned helplessness study (Miller & Seligman, 1975) with Israeli student nurses. The inescapable noise was presented either as a personally important task or as an unimportant task. When later tested on a series of 20 patterned anagrams, no performance differences were found between depressed and nondepressed Ss as was found in previous studies, nor did the importance manipulation affect performance. Within the depressed group only, it was found that the more the Ss believed they had control over the noise, the better was their performance in the anagrams. Similarly, only among the depressed was the rated aversiveness of the noise positively related to anagram performance. Depressed were only able to assess accurately the number of failures on the anagrams, while nondepressed did equally well in assessing both positive and negative aspects of their performance. The results are discussed in terms of Seligman's learned helplessness model of depression and Beck's cognitive model of depression.
