Introduction: Herein, we analyzed the histopathological, oncological and functional outcomes of testis-sparing surgery (TSS) in patients with distinct risk for testicular cancer. Methods: This is a multicenter retrospective study on consecutive patients who underwent TSS. Patients were categorized in high- or low-risk testicular germ cell tumor (TGCT) according to the presence/absence of features compatible with testicular dysgenesis syndrome. Histology was categorized per size and risk groups. Results: TSS was performed in 83 patients (86 tumors) of them, 27 in the high-risk group. Fifty-nine patients had a non-tumoral contralateral testis present. Sixty masses and 26 masses were benign and TGCTs, respectively. No statistical differences were observed in mean age (30.9 ± 10.32 years), pathological tumor size (14.67 ± 6.7 mm) between risk groups or between benign and malignant tumors (p = 0.608). When categorized per risk groups, 22 (73.3%) and 4 (7.1%) of the TSS specimens were malignant in the high- and low-risk patient groups, respectively. Univariate analysis showed that the only independent variable significantly related to malignant outcome was previous history of TGCT. During a mean follow-up of 25.5 ± 22.7 months, no patient developed systemic disease. Local recurrence was detected in 5 patients and received radical orchiectomy. Postoperative testosterone levels remained normal in 88% of those patients with normal preoperative level. No erectile dysfunction was reported in patients with benign lesions. Conclusion: TSS is a safe and feasible approach with adequate cancer control, and preservation of sexual function is possible in 2/3 of patients harboring malignancy. Incidence of TGCT varies extremely between patients at high and low risk for TGCT requiring a careful consideration and counseling. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the potential significance of the second transurethral resection of a bladder tumor (TURBT) in a population of patients whose primary pathology was high-grade pTa (Ta/HG) and who had received Bacillus Calmette-Guérin (BCG) treatment for at least 12 on oncological outcomes, based on the presence or absence of detrusor muscle. Materials and Methods: Patients with primary Ta/HG tumors (n=207) that met the inclusion criteria were grouped based on the presence of muscle tissue in the first TURBT and whether the secondary TURBT was performed. Progression, recurrence, and disease-free survival rates were compared between the groups. Results: Median follow-up period was 24 (12-205) months. In cases with muscle in the first TURBT, a second TURBT significantly increased the median disease-free survival time compared with those that did not undergo the second TURBT [32 months (12-83) vs 12 months (6-67); p<0.005]. In cases without muscle in the first TURBT, the second TURBT significantly reduced the rate of progression (p<0.05). Regression analysis showed that tumor size >3 cm [95% confidence interval (CI)=1.09-2.96, hazard ratio (HR)=1.79, p=0.021], presence of muscle tissue (95% CI=0.35-0.92, HR=0.57, p=0.022), and multiple tumor (95% CI=1.06-2.90, HR=1.75, p=0.028) were independent factors affecting disease relapse in primary Ta/HG tumor. Conclusions: In patients with primary Ta/HG tumors, if there was no muscle in the first TURBT, a second TURBT should be performed to achieve lower progression rates. If there is muscle in the first TURBT, the second TURBT will only increase the median disease-free survival time. [ABSTRACT FROM AUTHOR]

Objective: Coronavirus disease-2019 (COVID-19) pandemic changed various priorities in health area. Many elective surgeries for renal cell cancers (RCC) have been postponed. We examined the influence of the COVID-19 pandemic on the surgical treatment of RCC in Turkey. Materials and Methods: Surgically treated 457 patients for kidney tumor, from March 1, 2019 to February 28, 2021 in 9 centers in Turkey were analyzed retrospectively. Results: The number of surgical treatments for RCC during the COVID-19 pandemic has decreased significantly, in contrast to the same period before COVID-19. Admission symptoms were similar in these two periods (p=0.32). However, although not statistically significant, the rate of admission to hospital due to hematuria was higher during the pandemic period compared to the prepandemic period (14.4% vs 9.8%, respectively). The two study periods differed significantly in terms of the rate of metastatic RCC detected in preoperative imaging (13.1% vs 6.1%, during COVID-19 and pre-COVID-19, respectively) (p=0.01). Moreover, the study periods differed significantly in terms of time between imaging and operation [35 (2-240) vs 30 (1-210) days, during COVID-19 and pre-COVID-19, respectively] (p=0.01). However, these two periods were similar in terms of tumor size, type of surgery, and pathological stage (p≤0.05). Although the pathological stages were similar among the groups, nephrectomies due to the metastatic disease were significantly higher in the pandemic period (p=0.01). Conclusion: The number of RCC-related surgeries were significantly decreased during the pandemic period. However, the rate of surgery for metastatic disease has significantly increased.

Objective: Falls are a significant cause of morbidity and mortality, particularly in hospitalized patients. In this study, we aimed to evaluate the risk of falls in the patients hospitalized in a urology clinic. Materials and Methods: The study included patients that were hospitalized in a urology clinic between November and December 2018. All the patients were administered both Itaki Fall Risk scale (IFS) and Morse Fall scale (MFS). Demographic and clinical characteristics, history of falls within the past six months, type of surgery, primary diagnosis (urooncological vs non-urooncological), and the department/unit from which the patients were referred [outpatient clinic vs emergency service/intensive care unit (ICU)] were recorded. Results: The risk of falls was significantly higher in the patients with urooncological diseases compared to the patients with non-urooncological diseases (p<0.001) and in the patients referred from emergency service/ICU compared to the patients referred from outpatient clinics (p<0.001). Moreover, the patients with a history of falls within the past six months were found to be at higher risk of falls compared to the patients with no history of falls both on IFS and MFS (p=0.002, p=0.01, respectively). Conclusion: Hospitalized patients should be closely followed due to the risk of falls, particularly the cancer patients and the patients referred from the emergency service or ICU.

Objective: To evaluate the effect of prostate-specific antigen (PSA) fluctuation on Gleason score (GS) upgrading, disease upstaging, oncological outcomes in low-risk prostate cancer (PCa) patients who underwent robot-assisted laparoscopic radical prostatectomy (RARP) and met the inclusion criteria for active surveillance (AS). Material and methods: Data of 354 low-risk PCa patients who underwent RARP were retrospectively evaluated. Patients were divided into two groups: PSA fluctuation rate<9.5%/month (Group 1, n=192) and >9.5%/month (Group 2, n=162). Mainly compared parameters were GS upgrading, disease upstaging, biochemical recurrence (BCR) and surgical margin positivity (SMP) rates. Results: GS upgrading, disease upstaging and SMP were detected in 128 (36.2%), 56 (15.8%) and 42 (11.9%) patients, respectively. After a median follow-up of 46 months, BCR was observed in 40 (11.3%) patients. GS upgrading (41.1% vs. 30.2%, p=0.033), disease upstaging (19.8% vs. 11.1%, p=0.028), SMP (15.1% vs. 8%, p=0.035) and BCR development (15.6% vs. 6.2%, p=0.005) rates were statistically significantly higher in Group 1 than Group 2. In multivariate analysis, digital rectal examination positivity, the presence of two positive cores and low PSA fluctuation rate were found to be significant predictors of GS upgrading. Conclusion: Low PSA fluctuation rate is associated with higher GS upgrading. [ABSTRACT FROM AUTHOR]

Purpose: We analyzed the role of oxidative stress in detrusor overactivity (DO) by measuring serum total antioxidant capacity (TAC), total oxidant status (TOS), binding capacity of exogenous cobalt to human albumin (IMA), serum advanced oxidation protein products (AOPP), paraoxonase (PON), and arylesterase.Materials and Methods: The study included 38 female patients diagnosed with DO and 29 healthy female subjects forming the control group. Serum total antioxidant capacity (TAC), total oxidant status (TOS), binding capacity of exogenous cobalt to human albumin (IMA), serum advanced oxidation protein products (AOPP), paraoxonase (PON), and arylesterase were analyzed. The results of serum TAC, TOS, IMA, AOPP, PON, and arylesterase of the subjects in both groups were compared.Results: There was no difference between the groups in terms of age. When compared to the control group, serum TAC and IMA levels were statisticaly lower (P  < 0,001)  and higher (P = 0,003), respectively. However, TOS, AOPP, PON, arylesterase levels were similar in both groups ( p > 0.05 ).Conclusion: There seems to be an association between DO and oxidative damage according to our results, this can be measured by analyzing TAC and IMA in this patient group.

Objective: This study presents the surgical, oncological, and functional outcomes of the first 93 robotic radical prostatectomy (RARP) procedures performed in Erzurum, Turkey. These procedures were performed by a single surgeon who had completed the European Association of Urology Robotic Urology Section (ERUS) RARP curriculum in an ERUS-certified training center in Ankara. Material and methods: The study present the results of 93 RARP procedures performed by a single surgeon. The surgeon performing the operations completed an ERUS training program structured for RARP by two robotic surgeons holding ERUS training certificates in an ERUS-approved academic robotic surgery training center in Ankara.The RARP cases performed by the surgeon after completion of the training between April 2016 and August 2018 were retrospectively evaluated. Results: The mean patient age was 63.62±7.04 years, and the mean preoperative serum prostate-specific antigen level was 8.34±4.96 ng/mL. Preoperatively, 82 and 4 patients had prostate biop sy Gleason scores of 3+3 and 4+3, respectively. Bilateral neurovascular bundle (NVB) sparing, unilateral NVB-sparing, and non-NVB-sparing surgery were performed in 21, 13, and 59 cases, respectively. The mean prostate weight was 85.34±47.57 g. Posterior rhabdosphincter reconstruction was performed in 60 (64.5%) cases. Mean console time, intraoperative blood loss, duration of hospital stay, and urethral catheter removal time were 170.49±36.50 min, 100.70±34.08 cc, 6.84±2.28 days, and 7.40±3.11 days, respectively. During the perioperative period (0--30 days), five minor (prolonged drain output, n=3; rectocele, n=1; gout arthritis, n=1) and six major (inguinal hernia, n=1; incisional hernia, n=2; anastomotic urinary leakage, n=2; myocardial infarction, n=1) complications were identified. No complication was detected during postoperative days 31--90. Postoperative pathological stages included pT2a, pT2b, and pT2c disease in 77 (82.8%), 9 (9.7%), and 7 (7.5%) patients, respectively. The positive surgical margin (SM) rate was 10.7% (n=10), including patients with pT2a (n=6) and pT2c (n=2) diseases. Eleven (11.8%) patients underwent pelvic lymph node (LN) dissection. The mean LN yield was 16.45±4.29. The mean length of follow-up was 11.17±8.01 months. Biochemical recurrence was observed in two patients, one of whom received maximal androgen blockage (MAB), and the other one received pelvic radiotherapy+MAB. All the patients with at least one-year follow-up (n=48, 51.6%) were fully continent (0 pads/day). Of the 40 (43%) patients with no preoperative erectile dysfunction (ED) and with at least three-month follow-up, 18 (45%) had no ED, with or without any additional medication including phosphodiesterase-5 (PDE5) inhibitors. Conclusion: RARP is a safe minimally invasive procedure with acceptable morbidity, excellent operative, pathological and oncological outcomes, and satisfactory functional results. The ERUS RARP curriculum provides effective and sufficient training. [ABSTRACT FROM AUTHOR]

Introduction: We present oncological and functional outcomes of patients who underwent testis-sparing surgery (TSS). Methods: Overall, 13 patients were included. Mean patient age was 29.9±12.5 years. In five patients, TSS was performed for sequential bilateral testicular tumours. One patient underwent concurrent left radical orchiectomy and right TSS. In eight patients with normal contralateral testis, seven underwent left and one underwent right TSS. Results: Mean pathological tumour size was 14.6±12.5 mm. Intraoperative frozen section evaluation of the mass was performed in eight patients that revealed benign lesions. No intraoperative tumour bed biopsies were taken in this patient group. Regarding the remaining five patients, intraoperative tumour bed biopsies were taken and testicular intraepithelial neoplasia (TIN) was reported in two (40%) patients; no local testicular radiotherapy was given postoperatively. Tumour pathology was malignant in all but one lesion, including Leydig cell tumour (n=1), seminoma(n=2), embryonal carcinoma (n=1), and adenomatoid tumour (n=1). During 47.2±22.5 months of followup, local recurrence was detected in one patient who underwent radical orchiectomy. No additional local recurrence or systemic metastasis was identified in other patients with malignant lesions. For patients with malignant tumours, of the three patients with a normal preoperative testosterone levels, testosterone level was normal in one patient (with no erectile dysfunction [ED]) and was decreased in two patients (with ED) following TSS. No ED was reported in the nine patients with benign lesions. Conclusions: In carefully selected cases, TSS appears to be a safe, feasible procedure with adequate cancer control that could preserve sexual function. [ABSTRACT FROM AUTHOR]
