Comparison Between Retrograde and Antegrade Ureteroscopic Laser Lithotripsy for the Management of Medium-Sized Proximal Ureteral Stones: A Randomized Prospective Study.

Objectives: This study aimed to present the outcomes of retrograde and antegrade ureteroscopic laser lithotripsy in the treatment of proximal ureteral stones ranging in size from 10 to 20 millimeters in diameter.

Patients And Methods: From March 2023 to December 2023, 70 patients were included in this prospective randomized double-arm interventional study. Patients were divided into two groups: Group 1 (35 patients) had semi-rigid retrograde ureteroscopic laser lithotripsy, and Group 2 (35 patients) had semi-rigid antegrade ureteroscopic laser lithotripsy.

Recent advances in three-dimensional ultrasound virtual cystoscopy in modeling and local staging for urothelial carcinoma with histopathological correlation: a cohort prospective study.

Background: Bladder urothelial carcinoma is an alarming urologic malignancy. Complex factors like modelling and local staging can affect treatment strategy. However, local staging, particularly the muscle invasion status, significantly influences decisions regarding treatment strategies.

The outcomes of flexible ureteroscopy for renal calculi of 2 cm or more with and without the use of ureteral access sheath: A retrospective study.

Introduction: The rate of success of retrograde intrarenal surgery (RIRS) for treating urinary tract stones is high, and the procedure is growing in popularity. The routine use of ureteral access sheath (UAS) remains somewhat controversial. The aim of this study was to assess the efficacy and safety of employing UAS during flexible ureteroscopy for treating renal stones ≥ 2 cm.

HER2/neu expression status of post BCG recurrent non-muscle-invasive bladder urothelial carcinomas in relation to their primary ones.

Background: Transurethral resection (TUR) followed by adjuvant therapy is still the treatment of choice of Non-Muscle-Invasive Bladder Urothelial Carcinoma (NMIBUC). However, recurrence is one of the most troublesome features of these lesions. Early second resection and adjuvant BCG therapy has been shown to improve the outcome.

Comparative study between ureter first approach and conventional open Anderson-Hynes pyeloplasty in paediatric patients: A prospective randomised study.

Background: Uretero-pelvic junction obstruction is the most common form of congenital anomaly of the kidney and urinary tract with an incidence of about 1/1.000-1.500 of births and the aetiology and pathogenesis of this anomaly are still unclear until now.

Impact of extensive laparoscopic venous disconnection on the recurrence rate and sperm DNA quality in infertile varicocele patients.

Introduction: Although there are many literature examining the possible effects of varicocelectomy on classic semen parameters and recurrence rate, few published articles have examined the effect of conventional laparoscopic varicocelectomy on sperm DNA integrity.

Objectives: The objective was to evaluate the effect of extensive laparoscopic venous disconnections on the recurrence rate and sperm DNA damage in varicocele patients.

Methods: Totally, 54 patients with varicocele underwent extensive laparoscopic venous disconnections were assessed by clinical evaluation, duplex scan, semen analysis, and sperm DNA fragmentation assay before surgery and after 6 and 12 months following surgery.
