OBJECTIVES To evaluate semirigid retrograde ureteroscopy complications on a significant series of patients and to establish the factors associated with the occurrence of intraoperative complications. PATIENTS AND METHODS Between June 1994 and June 2013, 8150 semirigid ureteroscopic procedures for ureteral lithiasis were performed in 7456 patients. We used semirigid ureteroscopes(8 9.8F Wolf, ...

BACKGROUND There are many options for urologists to treat ureteral stones that range from 8 mm to 15 mm, including ESWL and ureteroscopic holmium laser lithotripsy. While both ESWL and ureteroscopy are effective and minimally invasive procedures, there is still controversy over which one is more suitable for ureteral stones. OBJECTIVE To perform a retrospective study to compare the efficiency...

introduction: surgical management of pediatric urinary calculi evolved dramatically over the past two decades. however, with the miniaturization of equipment and with improvisation of endourologic techniques, access to the entire pediatric urinary system is possible. ho: yag laser provides more maneuverability during transuretereal lithotripsy (tul) than the pneumatic system which uses a metal ...

We report a case of ureteral migration of a surgical clip after partial nephrectomy in which the clip was misdiagnosed as a ureteral stone. A 37-year-old woman had undergone laparoscopic partial nephrectomy of right renal cell carcinoma at another hospital 2 years previously. Postoperatively, she had gradually acquired lower urinary tract symptoms. Then, she complained of sudden right flank pai...

PURPOSE To assess the efficacy of extracorporeal shockwave lithotripsy (ESWL) for ureteral calculi during acute renal colic. MATERIALS AND METHODS From January 2002 to March 2007, 108 patients were treated by ESWL for obstructing ureteral stones causing acute renal colic. ESWL was performed within 24 hours of the onset of renal colic. RESULTS The mean age of the patients was 39.5 years (11-...

A 28-year old man presented with left flank pain and dysuria. Plain abdominal film and computed tomography showed a left giant ureteral stone measuring 11.5 cm causing ureteral obstruction and other stones 2.5 cm in size in the lower pole of ipsilateral kidney and 7 mm in size in distal part of right ureter. A left ureterolithotomy was performed and then a double J stent was inserted into the u...

from july, 1987 to oct, 1989 , 104 patients underwent 111 transurethral ureteroscopy procedures at the air force medical center. all intramural ureters were dilated by flexible metal dilators. the overall success rate for ureteral stone removal was 95.8 per cent. ureteroscopy was done for evaluation of gross hematuria, strictures, ureteral stent, and ureteral and pyelocalyceal tumors. the overa...

INTRODUCTION We present our experience with the use of semirigid ureteroscopy for the treatment of ureteric stones in children less than or equal to 6 years of age. MATERIAL AND METHODS The records of 21 children (12 female, 9 male) with an average age of 4.7 years (range 8 months to 6 years) treated with semirigid ureteroscopy between June 2006 and July 2010 were reviewed. In 13 ureteral uni...

PURPOSE This study aimed to determine the predictors of ipsilateral hydronephrosis after ureteroscopic lithotripsy for ureteral calculi. MATERIALS AND METHODS From January 2010 to December 2014, a total of 204 patients with ureteral calculi who underwent ureteroscopic lithotripsy were reviewed. Patients with lack of clinical data, presence of ureteral rupture, and who underwent simultaneous p...

PURPOSE We examined patient satisfaction with treatment outcomes after shock wave lithotripsy (SWL) and ureteroscopic removal of stone (URS) for proximal ureteral stones. MATERIALS AND METHODS We evaluated 224 consecutive patients who underwent SWL (n=156) or URS (n=68) for a single radiopaque proximal ureteral stone. Stone-free rates, defined as no visible fragment on a plain X-ray; complica...
