Thulium laser resection versus conventional transurethral resection of urinary bladder tumor: A comparative prospective study.

Background: Transurethral resection of bladder tumors (TURBT) is the standard management for urinary bladder tumors; however, new techniques as Thulium laser resection of bladder tumors (TmLRBT) have been introduced as a substitute to TURBT.

Objectives: In this study safety, efficacy, and tumor recurrence after TmLRBT and TURBT were prospectively compared in patients with primary (<4 cm) bladder tumors.

Patients And Methods: Between August 2019 and May 2021, patients with primary (<4 cm) bladder tumors were enrolled.

Randomized comparison of 4.5/6 Fr versus 6/7.5 Fr ureteroscopes for laser lithotripsy of lower/middle ureteral calculi: towards optimization of efficacy and safety of semirigid ureteroscopy.

Background And Purpose: To compare 4.5/6 Fr versus 6/7.5 Fr semirigid ureteroscopes in terms of safety and efficacy in adult non-obese patients with middle or lower ureteric stones.

Ergonomics and musculoskeletal symptoms in surgeons performing endoscopic procedures for benign prostatic hyperplasia.

Background And Purpose: Benign prostatic hyperplasia (BPH) is the most common urologic disorder affecting older men, necessitating medical or surgical intervention. Limited data exists regarding the effect these surgeries have on the endourologist's musculoskeletal system following the surgery because of the required difficult posture, prolonged procedures, repetitive movements, and the settings of an adjustable visual display terminal workstation. The aim of our study was to survey the prevalence and possible causes of musculoskeletal disorders among endourologists performing transurethral resection of the prostate (TURP) or laser prostatectomy using either holmium laser enucleation or thulium laser enucleation.

The safety of ureteral stenting with the use of potassium citrate for management of renal uric acid stones.

Objectives: The objective is to evaluate the relative risks of ureteric stents application while managing uric acid stones with potassium citrate in terms of stone encrustations and urinary tract infection (UTI).

Patients And Methods: We prospectively enrolled patients with renal uric acid stones who received K citrate from 2013 to 2018. Patient's demographics were collected.

Influence of postnatal hydroureter in determining the need for voiding cystourethrogram in children with high-grade hydronephrosis.

Objective: To evaluate the utility of hydroureter (HU) to identify high-grade vesico-ureteric reflux (VUR) in patients with high-grade postnatal hydronephrosis (PH).

Patients And Methods: We retrospectively reviewed patients' charts that had antenatal hydronephrosis from 2008 to 2014. Patients were excluded if they presented with febrile urinary tract infection (fUTI), neurogenic bladder, posterior urethral valve, multi-cystic dysplastic kidney, and multiple congenital malformations.

Mature Cystitic Teratoma of the Bladder Masquerading as a Distal Ureteral Stone.

A 27-year woman presented with irritative lower urinary tract symptoms and alleged small right distal ureteric stone that had been diagnosed with KUB and non-contrast spiral CT. Patient was scheduled for ureteroscopic lithotripsy, revealing absence of the presumed stone, while cystoscopy showed unexpected 2 cm pedunculated grayish white lesion, situated on the right lateral wall of the bladder with sparse hairs covering it. An incomplete TURBT was done; the histological findings correlated with the gross picture seen on cystoscopy.

Management of equivocal (early) Fournier's gangrene.

Background: Fournier's gangrene (FG) is an acute progressive necrotizing fasciitis of the genital area and perineum with possible extension to the abdominal wall. Surgical debridement is the gold standard management modality of established patients. Equivocal (early) FG represents a challenge in diagnosis.
