To investigate whether benign or malignant cells are present in gas evacuated from the abdominal cavity during oncologic laparoscopic surgery. Thirty patients were included in this prospective observational study conducted at an academic, tertiary medical center. Fifteen patients underwent a laparoscopic staging procedure for high-grade uterine adenocarcinoma and 15 patients underwent laparoscopic nephrectomy for suspected renal cell carcinoma. The gas evacuated during laparoscopy was passed through a filter in order to capture any aerosolized cells formed during surgery. After surgery, the filter was rinsed backwards with 50 mL of saline, and the fluid was centrifuged and sent for cytological evaluation. The primary outcome was presence of benign or malignant cells in the rinsed fluid. Neither benign nor malignant cells were identified in evacuated gas in 29 cases (96.7%). In one endometrial cancer case, where macroscopic extra-uterine pelvic metastases were encountered intra-operatively, atypical epithelial cells were found in collected fluid of rinsed gas filter. Gas insufflation during laparoscopy for gynecologic and urologic malignancies apparently does not cause aerosolization and dissemination of malignant cells. However, laparoscopic surgery itself may cause cell spread possibly via surgical instruments when macroscopic, extra-organ tumor spread is encountered, the clinical significance of which remains undetermined.

Objective: To assess a novel combined laser suction handpiece (LSH) for performing PCNL in a clinical setting. Methods: The study comprised 40 consecutive PCNLs performed between May 2019 and February 2020. The first 20 procedures (Group A) were performed with conventional ultrasonic or pneumatic devices and the other 20 (Group B) were performed with the use of the new LSH. All patients were treated by tubeless supine PCNL. The groups were compared for demographics, clinical data, operative time, lithotrite effectiveness, stone clearance rate (SCR), and outcome. Results: Groups A and B were similar in age, and in stone size, complexity, and density (Hounsfield units) (p < 0.05). The average operative time was 99 and 78 min, SCR 143 and 200 mm3/min, hospital stay 1.6 and 1.1 days, and stone-free rate 90% and 95%, respectively. Despite a trend toward better results with the new LSH, none of these comparisons reached statistical significance. Ineffective lithotripsy with the initial device (ultrasonic) requiring conversion to another modality (ballistic) occurred in six (30%) procedures in Group A, while all procedures were effectively accomplished with the LSH in Group B (p = 0.02). There were two complications in Group A and none in Group B (p > 0.05). Conclusions: The LSH is as effective and safe as the traditional lithotrites for performing PCNLs. This new tool completes the capabilities of the holmium laser high-power machines, enabling them to serve as the sole platform for all endourological treatments. [ABSTRACT FROM AUTHOR]

Background: Patients hospitalized due to gross hematuria frequently complete evaluation in the outpatient setting. The use of office flexible cystoscopy during hospitalization may lead to prompt diagnosis and treatment but can be limited due to low visualization and artifacts that can hamper diagnostic ability. Objective: The objective of this study was to assess flexible cystoscopy findings and yield performed in patients hospitalized due to gross hematuria. Methods: Medical records of patients who underwent flexible cystoscopy while hospitalized during September 2018–December 2019 were reviewed. Cystoscopic findings were categorized into (1) suspicious mass in the bladder or prostate, (2) nonsuspicious changes in the bladder, and (3) nondiagnostic exam. Descriptive statistics were used to report the clinical characteristics of the study cohort and the findings of cystoscopy. Univariate logistic regression analyses were used to identify predictors of malignant findings. Results: The study cohort consisted of 69 patients (median age of 76 years). Initial cystoscopy findings were suspicious for malignancy in 26/69 patients (38%), nonsuspicious for malignancy in 34/69 patients (49%), and nondiagnostic in 9/69 patients (13%). The median follow-up time was 9 months (range 4–14 months). Twenty patients (29%) were diagnosed with malignancy (sensitivity of 75% and specificity of 78%). The procedure led to either diagnosis or treatment of 39 patients (57%). However, in 30 patients (43%), the initial cystoscopy did not aid in the diagnosis, led to misdiagnoses, or required a follow-up cystoscopy. On univariate analyses, none of the precystoscopy variables were predictive of bladder malignancy. Conclusion: Flexible cystoscopy in the setting of acute hematuria requiring hospitalization did not lead to diagnosis or treatment in over 40% of cases. In this setting, consideration should be given to performing an upfront cystoscopy under anesthesia. [ABSTRACT FROM AUTHOR]

There are several studies on patients’ preference for same-gender physicians, especially female preference for same-gender gynecologists. Data regarding the preferences of urology patients, of whom the majority are males, are scarce. The objective of this study is to assess provider gender preference among urology patients. One hundred and nineteen consecutive men (mean age 57.6 years) who attended a urology clinic in one university-affiliated medical center were prospectively enrolled. A self-accomplished 26-item anonymous questionnaire was used to assess patients’ preferences in selecting their urologist. Of the 119 patients, 51 (42.8%) preferred a male urologist. Patients exhibited more same-gender preference for physical examination (38.3%), or urological surgery (35.3%), than for consultation (24.4%). Most patients (97%) preferred a same-gender urologist because they felt less embarrassed. Four patient characteristics were identified to be significantly associated with preference for a male urologist: religious status, country of origin, marital status, and a prior management by a male urologist. Of these, religious status was the most predictive parameter for choosing a male urologist. The three most important factors that affected actual selection, however, were professional skills (84.6%), clinical experience (72.4%), and medical knowledge (61%), rather than physician gender per se. Many male patients express gender bias regarding their preference for urologist. However, professional skills of the clinician are considered to be more important factors when it comes to actually making a choice. [ABSTRACT FROM AUTHOR]

Aim Methods Results Conclusions The value of post‐operative pelvic drain placement after robot‐assisted radical prostatectomy (RARP) for the purpose of diagnosing post‐operative complications is undetermined. The aim of this study was to assess the yield of pelvic drain outputs in predicting post‐operative early‐onset urinary leaks from a vesicourethral anastomosis.We conducted a retrospective analysis of 204 consecutive patients who underwent RARP in our institution between 2018 and 2022. The daily outputs of the drain and the urinary catheter were measured, and patients with early‐onset anastomotic urinary leak were compared with those who were free of any leak. The association between post‐operative drain output and the presence of urinary leak was investigated by regression analyses.Post‐operative early‐onset leak was present in six patients (3.4%) whose baseline characteristics were not different from those of patients with no leak. The median pelvic drain output on post‐operative day 1 (D‐POD1) was 80 mL (interquartile range [IQR] 51–150 mL) and 122 mL (IQR 62–200 mL) on D‐POD2. The median D‐POD1 of patients with a leak was significantly higher than those without one (250 mL vs 80 mL, respectively; P < .001). The threshold to predict an anastomotic urinary leak was 227 mL on D‐POD1 (area under the curve 0.88; P < .001), and an association between D‐POD1 >227 mL and the presence of urinary leak (odds ratio 35; P < .001) was found.Pelvic drain output on POD1 can predict early‐onset urinary leak. Given the relatively low rate of this complication via a robotic approach, however, we consider that, unless otherwise indicated, the routine placement of a pelvic drain may be safely avoided.

Background: Tubeless percutaneous nephrolithotomy is defined as PCNL without postoperative nephrostomy tubes. It is reported to reduce postoperative pain, hospital stay and recovery time. To date the procedure has been reserved for selected patients., Objectives: To assess our initial experience in extending the implementation of tubeless PCNL without preoperative patient selection., Methods: All consecutive PCNLs performed during 2004-2008 were evaluated. Tubeless PCNL was performed when residual stones, bleeding and extravasation were excluded intraoperatively. Staghorn stones, stone burden, supracostal and multiple accesses, anatomic anomalies, solitary kidneys and operative time were not considered contraindications. We analyzed the clinical data and the choice of tubeless PCNL over time., Results: Of 281 PCNLs performed during the study period 200 (71%) were tubeless. The patients' average age was 53 years (range 28-82 years), the stone burden was 924 mm2 (400-3150 mm2), operative time was 99 minutes (45-210 min), complication rate was 14% and immediate stone-free rate 91%. There were 81 conversions to standard PCNL (29%) due to expected second-look (n = 47, 58%), impression of bleeding (n = 21,26%), suspected hydrothorax (n = 7, 9%) and extravasation (n = 6, 7%). The transfusion rate was 1%. The median hospital stay was 1 day (1-15 days) and recovery time 7 days (5-20 days). The rate of implementing the tubeless procedure increased steadily along time from 46% to 83% (P = 0.0001)., Conclusions: Tubeless PCNL can be safely and effectively performed based on intraoperative decisions, without preoperative contraindications. They are easily accommodated by experienced endourologists and provide real advantages.

Objectives: Numerous publications from Europe and North America show an increase in the incidence of testicular cancer in past years with substantial differences within and among the different countries. This study aimed to evaluate testicular cancer incidence and other epidemiologic characteristics in Israel in recent years., Methods: Incidence data was retrieved from the Israeli National Cancer Registry database. Patients with primary testicular cancer diagnosed in the years 1992-2002 were evaluated. For the sample of the year 2002, cross reference and deeper epidemiologic characterization using hospital archives was performed. Incidence rates were calculated according to age standardized, world population based standard. Analysis of variables of age, religion, origin, occupation, risk factors and histological subtypes was performed., Results: In the period of 11 years, 983 primary testicular cancer cases were diagnosed in Israeli citizens. Among Jewish men the incidence rate rose from 2.16 to 4.23/100000 while in Arabs it rose from 0.2 to 1.89/100000. Within the Jewish population the incidence rate elevation was notably prominent in immigrants from Asia and Africa. Considering the geographic distribution, in the Northern Negev changes in incidence rate were found to be more noticeable. A statistically significant decrease in the disease presentation age was observed. Germ cell testicular tumors are a leading cause of the process with an elevation of 86.2% in incidence rate from 1992 to 2002., Conclusions: The incidence of testicular cancer has increased in Israel in recent years. This trend is strongly associated with previously reported data from economically developed countries. It varies between different population groups. No single hypothesis can be put forward to account for the sudden increase in the disease incidence.
