Background Men with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH), will have deterioration in the quality of life. Likewise, BPH can be complicated by damage to bladder function, bladder stones formation, hematuria, and impaired kidney function. The goal of treatment is to avoid all those effects caused by B...

Objective To assess the effect and outcome of percutaneous nephrolithotomy (PNL) versus extracorporeal shock wave lithotripsy (SWL) in patients with renal insufficiency.Patients and methodsA prospective randomized clinical study of 104 renal insufficiency patients with renal stones (serum creatinine 2–4 mg/dl and eGFR < 60 ml/min/1.73 m2 more than...

Background:In men, lower urinary tract symptoms (LUTS) are associated with benign prostatichyperplasia (BPH). Therapeutic options aim to relax prostate smooth muscle and/or reduce prostate enlargement. Objectives:To evaluate the efficacy of Silodosin 8 mgalone versus the combinationof Tadalafil 5mg and Silodosin 4 mgfor treatment of LUTS related to...

Background: The incidence of stone formation in patients with renal insufficiency 17.5%, complete clearance of stone in these patients need least invasive procedure with safety of kid-ney parenchyma and kidney function. Objectives:To analyze outcomes of percutaneous nephrolithotomy (PNL) and shock wave lithotripsy (SWL) and their effect on kidney f...

Objective To assess the effect of artificial hydronephrosis on the result of shock wave lithotripsy (SWL) in preschool children. Materials and methods A prospective randomized trial was performed between January 2013 and January 2017 with 300 pediatric patients, having kidney stones with a size of 1–2 cm and a density of 750–1100 HU. The patients...

Objective Peeping testis is an inconsistently palpable/seen undescended testis that migrates back and forth at the internal inguinal ring. Both open and laparoscopic orchiopexy are effective forms of management. The present study aimed to evaluate the efficacy and safety of both approaches. Patients and methods Between September 2007 and January 2...

Objective: To evaluate the safety and efficacy of percutaneous suprapubic stone extraction (PSPSE) for pediatric posterior urethral stones. Methods: Between July 2007 and June 2010, 54 boys presenting with acute urinary retention due to posterior urethral stones underwent PSPSE. Patients were a mean age of 66.4 months (range, 8-180 months). The...

To evaluate the safety and clinical efficacy of the transobturator vaginal tape ‘inside-out’ (TVT-O) procedure for managing new-onset stress urinary incontinence (SUI) after radical cystectomy (RC) and orthotopic W-neobladder construction in women.Patients and methodsBetween January 2004 and June 2010, 57 women were treated with RC and orthotopic i...

The continued evolution of stone treatment modalities, such as endourologic procedures, open surgery and shock wave lithotripsy, makes the assessment of continuous outcomes are essential. Pediatric urolithiasis are an important health problem allover the world, especially in Middle East region. We evaluate the safety, efficacy and factors affecting...

Objective To evaluate and update the clinical and surgical outcome of orthotopic diversion in an eligible cohort of women with bladder carcinoma.Patients and methodsFrom 1999 to 2010, 78 women (mean age 42.4 years) had a radical cystectomy (RC) with orthotopic diversion using ileal neobladder reconstruction to treat invasive bladder carcinoma. The...

To evaluate the use of buccal mucosa tubal graft for reconstruction of extensive ureteral stricture. Between April 2006 and July 2008, 5 patients (mean age, 51.2 years) underwent reconstructive ureteral surgery for ureteral obstruction using buccal mucosa graft. The indication of surgery was extensive ureteral stricture of a 4.4-cm average length (...

To evaluate the neourethra covering created by a vascularized overlapping double-layered dorsal dartos flap for preventing urethrocutaneous fistula in the Snodgrass hypospadias repair (tubularized incised plate). Between March 2003 and January 2008, 156 boys (mean age, 4.5 years) were enrolled for hypospadias repair. Preoperative position of the ur...

Background: Ureteral catheters are valuable indispensable devices may readily acquire biofilms on the inner or outer surfaces. This study evaluated the efficacies of ureteral catheters impregnated with ciprofloxacin, N-acetylcysteine each alone and in combination on microbial adherence. Methods: Antimicrobial durability of ureteral catheters coated...

We retrospectively evaluated our experience with a relatively uncommon procedure, the laparoscopic ureterolithotomy, for the treatment of ureteral stones. Between April 2002 and October 2006, a total of 74 patients (56 males, 18 females) with upper (54 cases), middle (18 cases) and lower (two cases) ureteral stones underwent laparoscopic ureterolit...

From May, 1999 to August, 2006, we performed laparoscopic diagnosis and treatment for 103 cases of impalpable testes. Among those we found 5 cases of male pseudohermaphroditism of different etiologies. Three males presented by impalpable testes with ambiguous genitalia and 2 females presented by primary amenorrhea. All of them have 46-XY normal mal...

To evaluate the potential role of tamsulosin in the medical treatment of distal ureteral stones. Ninety patients with symptomatic distal ureteral calculi were enrolled. They were randomly divided into two groups: Group A (n=45) received diclofenac 100 mg on demand for 4 weeks plus levofloxacin 250 mg daily for the first week and were well hydrated;...

To evaluate transperitoneal ureterolithotomy by laparoscopy (TPUL) for the management of recurrent lower-ureteral stones previously treated with open surgery. Between January 2003 and June 2006, 11 patients (mean age 35.2 years) with recurrent large (mean size 2.8 cm) lower-ureteral calculi and normal renal function underwent TPUL. Seven stones wer...

Treatment of patients with abdominal non-palpable testis (NPT) is still controversial among pediatric urologists. This is a prospective randomized comparative study between open and laparoscopic orchiopexy for management of abdominal testis. The aim of this study was to evaluate the success rate and morbidity of both approaches. Eighty-two patients...

To test the feasibility of using the penile corpora cavernosa for blood transfusion and resuscitation purposes. Three male donkeys were used for autologous blood transfusion into the corpus cavernosum during three sessions with a 1-week interval between each. Two blood units (450 mL each) were transfused per session to each donkey. Moreover, three...
