Purpose: To present a new protocol using antibiotic irrigation during lithotripsy in retrograde intrarenal surgery (RIRS) to provide sterility of the renal collecting system.

Methods: This prospective study included 102 patients who underwent RIRS between January 2022 and August 2023. The patients were examined in two groups as those who received antibiotic irrigation (n:51) and standard irrigation (n:51).

Article Synopsis
  • This meta-analysis investigates the effects of varicocoelectomy on sperm morphology specifically in patients with isolated teratozoospermia, a rare condition affecting sperm shape and quality.
  • Out of 1,013 studies screened, five met the inclusion criteria, involving 348 male patients, and found that varicocoelectomy significantly improved sperm morphology but showed no notable change in sperm concentration.
  • Additionally, the analysis indicated a high pregnancy rate among patients post-surgery, though potential publication bias was identified in the findings.

Objectives: Lower urinary tract symptoms due to benign prostatic hyperplasia in men increase with aging. Risks related to anesthesia and surgery have led a search for alternative treatments. Bipolar radiofrequency (RF) thermotherapy is one of the methods adopted in patients with high surgical risks.

Objective: The aim of this study was to explore the criteria that can predict bladder cancer among the lesions that could not be differentiated from intravesical prostate protrusion (IPP) and to create a scoring system using these criteria.

Methods: A retrospective analysis was made of patients with an ultrasound report indicating lesions in the bladder neck, for which differentiation between bladder cancer and IPP could not be determined. A total of 174 patients diagnosed with bladder cancer (n=102) or benign prostate lesion (n=72) according to the biopsy results were enrolled in the study.

Purpose: To evaluate the effect of the reverse Trendelenburg position in patients undergoing ureteroscopic lithotripsy for proximal ureteral stones.

Methods: The study included 167 patients who underwent ureteroscopic lithotripsy for proximal ureter stones between December 2020 and September 2022. The patients were randomly assigned to one of three groups: standard lithotomy (n:55), 10° reverse Trendelenburg (n:55), and 20° reverse Trendelenburg (n:57).

The prevalence of penile calcification in the population remains uncertain. This retrospective multicenter study aimed to determine the prevalence and characteristics of penile calcification in a large cohort of male patients undergoing non-contrast pelvic tomography. A total of 14 545 scans obtained from 19 participating centers between 2016 and 2022 were retrospectively analyzed within a 3-months period.

Introduction: The aim of the study was to determine the correlation between the dwelling time for a ureteral stent placed for passive dilation after impassable ureteroscopy and success and complications.

Methods: A retrospective evaluation was made of patients who underwent stent placement after impassable ureteroscopy and a repeat ureteroscopy due to kidney stones. A total of 161 patients were included in the study between 2015 and 2022.

Objective: We aimed to investigate the significance of time to re-staging transurethral resection (re-TUR) on recurrence and progression rates in patients with high-risk non-muscle-invasive bladder cancer as a prospective randomized study.

Methods: The patients were randomly separated into three groups according to Re-TUR timing. In Groups 1, 2, and 3, the time interval between initial and re-TUR was 14-28 days, 29-42 days, and 43-56 days, respectively.

Purpose: We aimed to investigate the effects of obturator nerve block (ONB) on obturator reflex, incomplete resection, perforation, progression and recurrence of tumor, presence of muscle tissue in the specimen, need for a second transurethral resection (TURBT) of bladder tumors, and postoperative complications in patients who underwent TURBT for intermediate-high risk lateral wall non-muscle invasive bladder cancers (NMIBC).

Material And Methods: Patients were assigned to one of two groups by drawing lots: ONB or none ONB. Early and late recurrence, tumor progression, obturator reflex beat, incomplete resection, perforation, presence of muscle layer in pathology, second TURBT application, operation time, postoperative hospital stay, and complications were compared between the two groups.
