Background: En-bloc resection of bladder tumors achieves complete tumor removal, improves the quality of resection, decreases perioperative complication, and potentially improves recurrence rates.
Objective: To assess the efficacy and safety of holmium laser en-bloc resection (HolERBT) versus conventional transurethral resection of bladder tumor (cTURBT).
Design, Setting, And Participants: Between September 2015 and September 2018, 100 patients with non-muscle-invasive bladder cancer were randomly allocated to cTURBT or HolERBT.
Objective: To compare transurethral resection in saline (TURIS), Greenlight laser vapo-enucleation of the prostate (GL.PVEP), and holmium laser enucleation of the prostate (HoLEP), for controlling lower urinary tract symptoms secondary to large benign prostatic hyperplasia (BPH) and to assess non-inferiority of 3-year re-treatment rates.
Patients And Methods: Eligible patients with BPH (prostate size 80-150 mL) were randomly assigned to one of the intervention groups.
: To evaluate the efficacy and safety of botulinum toxin A (BoNT-A) instillation in the bladder under the effect of low-energy shockwaves (LESWs) for the treatment of refractory idiopathic overactive bladder (OAB). : A preliminary clinical study was conducted, including 15 patients with refractory OAB, between September 2016 and July 2017. Intravesical instillation of 100 IU of BoNT-A was done followed by LESWs (3000 shocks over 10 min) exposure to the supra-pubic area.

Methods: The study included consecutive adult patients who underwent PNL for treatment of calculi in a solitary kidney between May 2012 and July 2015. Patients with congenital renal anomalies or with stages 4 and 5 chronic kidney disease (CKD) were excluded.
Objective: To compare high-power holmium laser lithotripsy (HP-HLL) and ultrasonic lithotripsy (US-L) for disintegration of staghorn stones during percutaneous nephrolithotomy (PCNL).
Patients And Methods: A non-inferiority randomised controlled trial was conducted between August 2011 and September 2014. Inclusion criteria were patients' aged >18 years who had complete staghorn stones (branching to the three major calyces), without contraindications to PCNL.
Objective: To compare the efficacy, safety and cost of extracorporeal shockwave lithotripsy (ESWL) and percutaneous nephrolithotomy (PNL) for treating a 20-30 mm single renal pelvic stone.
Patients And Methods: The computerised records of patients who underwent PNL or ESWL for a 20-30 mm single renal pelvic stone between January 2006 and December 2012 were reviewed retrospectively. Patients aged <18 years who had a branched stone, advanced hydronephrosis, a solitary kidney, anatomical renal abnormality, or had a surgical intervention within the past 6 months were excluded.
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.
Patients And Methods: A database was compiled from the computerised files of patients who underwent PCNL for staghorn stones between 1999 and 2009. The study included 238 patients (128 males and 110 females) with a mean (SD) age of 48.
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.
Background: Since introduction of Contemporary Epstein criteria, it has been studied and validated in many countries and nations. However, they were not validated in Middle East patients up till now.
Aim Of The Work: To validate the Contemporary Epstein criteria in Middle East patients.
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: 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.
Article Synopsis
- Gynecological and obstetric surgeries can lead to urinary tract injuries, with a study of 120 females over 18 years highlighting different types of injuries, including vesicovaginal and ureteric fistulas.
- Of the treated cases, 13.3% of vesicovaginal fistulae recurred, but there were no significant long-term kidney function losses linked to these injuries.
- The findings emphasize the importance of understanding urinary tract anatomy for prevention, and suggest that early intervention can effectively manage these surgical complications.
Purpose: To evaluate the surgical feasibility of laparoscopic adrenalectomy and what laparoscopy offers for the surgeon and the patient.
Patients And Methods: From March 1996 to June 2004, 43 transperitoneal laparoscopic adrenalectomies were performed for various pathological states. Functioning adrenal masses and solid masses>5 cm were the most common indications.
Laparoscopy has become a well-established alternative to open surgery for the management of many urologic tumors. Metastases at one of the port sites is not a common complication, though there are some reports of port site metastases after laparoscopic management for renal tumors and pelvicaliceal tumors, as well as after laparoscopic lymphadenectomy. Herein, we report a case of port site metastases after robot-assisted laparoscopic radical cystectomy for muscle-invasive bladder cancer.
