We report a case of primary small cell carcinoma of the ureter with squamous cell and transitional cell carcinomatous components associated with ureteral stone, which is unique in that the patient has remained free of tumor recurrence for 36 months after the surgery without adjuvant chemotherapy or radiotherapy. A 60-yr-old man presented himself with a right flank pain. Computed tomography reve...

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...

Double-J (DJ) stents are the main tools used in urological practice for prevention and treatment of obstruction. Stenting is also mandatory after complicated ureteroscopy or TUL (Transureteral Lithotripsy). Known complications are upper migration of DJ stents into the kidney and lower migration to the bladder. In a man with an impacted right lower ureteral stone, a DJ stent was placed because t...

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 ...

OBJECTIVE To evaluate the clinical efficiency of alpha1-adrenergic antagonists on stentless ureteroscopic lithotripsy treating uncomplicated lower ureteral stones. MATERIALS AND METHODS From January 2007 to January 2013, 84 patients who have uncomplicated lower ureteral stones treated by ureteroscopic intracorporeal lithotripsy with the holmium laser were analyzed. The patients were divided i...

OBJECTIVE To compare the risk of postoperative ureteral stricture formation following retroperitoneal laparoscopic ureterolithotomy (RPLU) and ureteroscopy with holmium: YAG laser lithotripsy (URSL) in patients with proximal ureteral stones. MATERIALS AND METHODS We retrospectively reviewed the medical records of patients who underwent RPLU or URSL for proximal ureteral stones between April 2...

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-...

OBJECTIVES In this study, we aimed to analyze the ureter stones that had been treated using rigid ureteroscopy and pneumatic lithotripsy without mechanically dilating the ureteral orifice. PATIENTS AND METHODS Records of 110 patients who had undergone rigid ureteroscopy and pneumatic lithotripsy due to ureteral stone between February 2005 and May 2011 were retrospectively analyzed. The locati...

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...
