Ureteroscopy in the elderly: safety and functional results.

Purpose: To evaluate the effectiveness and safety of ureteroscopy (URS) for urinary stones treatment in patients ≥ 80 years of age.

Methods: From 2012 to 2021, 96 patients ≥ 80 years underwent URS for urinary stone disease. Patients' demographics and surgical outcomes were examined.

The relationship between patients' kidney stone type and demographics in Israel: analysis of 10 K patients.

Purpose: To analyze urinary stone composition in Israel and assess the effects of key demographic parameters (gender, age, socioeconomic status, ethnicity, medical history and geographic region) on stone composition.

Methods: A retrospective review was conducted of stone analysis of 10,633 patients from an HMO Israeli database analyzed by a central laboratory from 2014 to 2019 and subjected to Fourier-transform infrared spectroscopy. Associations between stone composition and different demographic parameters were determined using the Chi-square test.

Obstruction of the ureter by neurofibroma of the urinary bladder treated endoscopically.

We present a case of a 23-year-old male with NF-1 diagnosed with bladder neurofibroma at childhood with regular ultrasound (US) follow-up since then, who presented with an obstructed left kidney. A detailed evaluation including blood tests and advanced imaging revealed left hydroureteronephrosis associated with a large bladder mass. The patient underwent cystoscopy and resection of the left ureteral orifice that was covered by the mass, and an indwelling ureteral stent was left in place.

Association between early change in neutrophil-to-lymphocyte ratio after radical cystectomy and treatment outcomes.

Objectives: To evaluate the associations of peri-operative neutrophil-to-lymphocyte ratio (NLR) and change in NLR with survival after radical cystectomy.

Patients And Methods: We retrospectively reviewed a multicentre cohort of patients with bladder cancer who underwent radical cystectomy between 2010 and 2020. Preoperative NLR, postoperative NLR, delta-NLR (postoperative minus preoperative NLR) and NLR change (postoperative divided by preoperative NLR) were calculated.

Very Low Prostate PET/CT PSMA Uptake May Be Misleading in Staging Radical Prostatectomy Candidates.

Purpose: to evaluate a unique subpopulation of radical prostatectomy (RP) candidates with “negative” prostate 68Ga-labeled prostate-specific membrane antigen (PSMA) positron emission tomography (PET) computed tomography (CT) imaging scans and to characterize the clinical implications of misleading findings. Materials and Methods: This case-control retrospective study compared the final histological outcomes of patients with “negative” pre-RP PSMA PET/CT prostate scans (with a prostate maximal standardized uptake value [SUVmax] below the physiologic uptake) to those with an “intense” prostatic tracer uptake (with a SUVmax above the physiologic uptake). The patients underwent an RP between March 2015 and July 2019 in five academic centers.

Comparison of Partial and Radical Laparascopic Nephrectomy: Perioperative and Oncologic Outcomes for Clinical T2 Renal Cell Carcinoma.

Introduction: Nephron-sparing surgery has emerged as the treatment of choice for small renal masses. However, its role in larger tumors remains controversial. In this study, we compare the outcomes of laparoscopic partial nephrectomy (LPN) vs those of laparoscopic radical nephrectomy (LRN) for T2 renal tumors.

Endothelial Function Assessment in Patients with Erectile Dysfunction.

Background: Erectile dysfunction (ED), a common problem in males of all ages, can be of organic, psychogenic or combined etiology. Organic ED is mainly caused by vascular and neurological disorders. One of the available tests for differentiating organic from inorganic ED is measuring penile tumescence and rigidity during the REM phase of sleep.
