Objective: To compare the outcome and morbidity of bipolar transurethral enucleation of the prostate (B-TUEP) and thulium laser enucleation of the prostate (ThuLEP) with those of holmium laser enucleation of the prostate (HoLEP) in the treatment of large symptomatic benign prostatic obstruction (BPO) through a non-inferiority randomized controlled trial (NCT03916536).
Patients And Methods: A total of 155 patients were recruited from a single centre between February 2019 and August 2020. All had BPO, with a prostate volume ≥80 ml.
Background: The aim of the present study was to develop and internally validate a simple stone score (SSS) to estimate the probability of clinically significant residual fragments (CSRF) prior to percutaneous nephrolithotomy (PNL).
Methods: The files of 1170 PNL procedures between January and December 2015 were evaluated. CT-derived stone characteristics were examined.
This study was conducted to evaluate preoperative risk factors for development of complications of percutaneous nephrolithotomy (PCNL). All consecutive patients aged ≥ 16 years who underwent PCNL during 2015 were retrospectively reviewed. Non-contrast CT (NCCT) was performed for all patients to evaluate stone complexity.

Patients And Methods: Between January 2015 and May 2017, patients who underwent RNU were randomized to receive SIC (epirubicin 50 mg) or MIC (once weekly for 6 weeks plus once monthly for 1 year). The primary outcome was the rate of histologically proven BR.
Objectives: To compare monopolar and bipolar transurethral resection of the prostate (M-TURP and B-TURP, respectively) focusing on erectile and ejaculatory functions in a randomized trial.
Methods: Between January 2013 and December 2014, all consecutive TURP candidates with benign prostatic hyperplasia (BPH) were prospectively randomized 1:1 into M-TURP/B-TURP arms and followed up at 2, and 4 weeks, 6 and 12 months after surgery. All patients were assessed using IIEF-15 (International index of erectile function-15) and Ej-MSHQ (ejaculatory domain-male sexual-health inventory).
Objective: To assess the non-inferiority of Low-power Holmium laser enucleation of the prostate (LP-HoLEP) to high-power (HP-HoLEP) for enucleation efficiency pertaining to the advantages of lower cost and minimal postoperative dysuria, storage symptoms, and negative sexual impact.
Patients And Methods: HoLEP was performed using 100W Versapulse, Luminis Inc., with 2J/25Hz for LP-HoLEP (61 patients) and 2J/50Hz for HP-HoLEP (60 patients).
Objective: The aim of this study was to compare the efficacy of antimicrobial [silver sulfadiazine (SSD)]-coated ureteral stents with non-coated stents in the prevention of stent-related bacteriuria.
Materials And Methods: A randomized controlled trial was conducted between September 2014 and September 2016 after approval from the local ethics committee. Inclusion criteria were adults who underwent unilateral double-J ureteral stent placement after ureteroscopic lithotripsy.
Objectives: To assess how much Holmium laser enucleation of the prostate (HoLEP) is detrimental on men sexuality.
Methods: Between January and December 2013, all patients presented for BPH surgery were assessed using IIEF-15 (international index of erectile function-15) and Ej-MSHQ (ejaculatory domain-male sexual health questionnaire). Changes in men's sexuality following HoLEP in relation to control procedure were prospectively assessed.
Objective: To evaluate the long-term functional outcome of percutaneous nephrolithotomy (PNL) for calculi in solitary kidneys and to determine factors leading to renal function deterioration.
Materials And Methods: The computerized files of patients with solitary kidneys who underwent PNL between January 2002 and December 2009 were retrospectively reviewed. Patients with follow-up <2 years were excluded.
Objective: To present the results of percutaneous nephrolithotomy (PCNL) for treating staghorn stones.

Objective: To determine factors affecting the stone-free rate and complications of percutaneous nephrolithotomy (PNL) for treatment of staghorn stones.
Methods: The computerized database of patients who underwent PNL for treatment of staghorn stones between January 2003 and January 2011 was reviewed. All perioperative complications were recorded and classified according to modified Clavien classification system.
Objective: • To study long-term results of percutaneous nephrolithotomy (PNL) for treatment of staghorn stones.
Patients And Methods: • The records of patients who underwent PNL for staghorn stones between January 1998 and January 2008 were retrospectively reviewed. • Patients who completed follow-up for one year or more were included.
Objective: To determine factors affecting the success of bilateral same-session ureteroscopy (BSU) in the treatment of ureteral calculi.
Material And Methods: From January 2003 to December 2008, BSU was carried out in 89 patients (178 renal units). A successful outcome was considered when both ureters were free of stones without intraoperative complications.
Objectives: To evaluate the role of percutaneous nephrolithotomy in management of the patients with autosomal dominant polycystic kidney disease and associated nephrolithiasis.
Methods: A total of 19 patients with autosomal dominant polycystic kidney disease and upper urinary tract stones were included in the study. One patient had bilateral renal stones.
Objectives: To use a matched-pair analysis design to compare the safety and efficacy of shock wave lithotripsy (SWL) and ureteroscopy (URS). Controversy still exists regarding whether SWL or URS is the best management of upper ureteral calculi.
Methods: We reviewed the records of patients with a single radiopaque upper ureteral stone treated by URS or SWL from January 2003 to December 2005.
Purpose: We determined the factors predicting unfavorable results of semirigid ureteroscopy for ureteral calculi.
Materials And Methods: We reviewed the computerized files of 841 patients who underwent a total of 908 ureteroscopic procedures for ureteral stones from January 2003 through December 2006. A semirigid 6/7.
Purpose: This study was conducted to evaluate the safety and efficacy of the supracostal approach for percutaneous nephrolithotomy in pediatric patients.
Materials And Methods: We retrospectively reviewed 60 percutaneous nephrolithotomy procedures done in 50 children (32 boys and 18 girls) between 2000 and 2007. Mean patient age was 7 +/- 4 years (range 9 months to 14 years).
Objectives: To evaluate the functional and morphological effects of postpercutaneous nephrolithotomy (PCNL) superselective renal angiographic embolization.
Methods: Between January 1995 and March 2006, superselective renal angiography was needed to control severe bleeding after 41 of 4095 PCNL procedures (1%). We evaluated the short-term effects of embolization after 3 months with renal ultrasonography (RUS), dimercaptosuccinic acid (DMSA) renal scan, and estimation of serum creatinine.
Purpose: To present the combination of laparoscopy and nephroscopy for the treatment of stones in pelvic ectopic kidneys.
Patients And Methods: The series included seven male and four female patients (mean age 43 +/- 9 years). Laparoscopy-assisted percutaneous nephrolithotomy (PCNL) was performed for caliceal stones in five patients after failure of shockwave lithotripsy, while laparoscopic pyelolithotomy was performed for large or branched renal pelvic stones in six patients.
Purpose: Despite evidence that urologists can safely acquire percutaneous renal access for percutaneous nephrolithotomy, many centers still rely on interventional radiologists to obtain renal access. In this study we evaluated percutaneous access for percutaneous nephrolithotomy obtained by interventional radiologists or urologists, and compared access outcomes and complications.
Materials And Methods: The surgical records of 1,121 patients with 1,155 stone bearing kidneys treated with percutaneous nephrolithotomy between 1999 and 2003 were reviewed.
Purpose: We identified risk factors predicting severe bleeding due to percutaneous nephrolithotomy.
Materials And Methods: Computerized data on 2,909 patients who underwent a total of 3,878 percutaneous nephrolithotomy procedures between January 1995 and December 2005 were retrospectively reviewed. Data on patients who experienced severe bleeding requiring angiographic renal embolization were compared with those on other patients using univariate and multivariate analyses.
Objective: The surgical management of renal and upper ureteral calculi presents unique challenges in obese patients. We reviewed our recent experience with percutaneous nephrolithotomy (PNL) in obese patients to determine the safety and outcome of this procedure in such group of patients.
