A 33-year-old male with an ileal conduit was referred to our department for the treatment of left renal calculi. After inserting a ureteral access sheath, a ureteroscopy-assisted retrograde nephrostomy was made. Percutaneous nephrolithotomy was successfully achieved using this nephrostomy.

Ureteral access is necessary in many endourological procedures including ureteroscopy and ureteral stenting. Technologies such as ureteral access sheaths, balloon dilators, and coaxial dilators may be helpful in facilitating ureteral access in difficult cases. This chapter describes a stenting technique that relies on fluoroscopic guidance once the initial guidewire is placed and the cystoscope...

This report documents two instances of retained flexible ureteroscopes at the time of ureteroscopy and laser lithotripsy in a healthy 37-year-old male and a 53-year-old male with a pelvic kidney. We describe maneuvers to remove the ureteroscope endoscopically in the first case, while the second case required conversion to open surgery for ureteroscope extrication.

Ureteral fibroepithelial polyps are a rather uncommon pathological entity. However, an increase of their incidence was recorded during the recent period, probably due to better access to the investigative methods. The aim of this study was to assess the diagnosis and endoscopic treatment particularities of these cases. Our experience was based on 11 cases evaluated in the last 12 years. The mea...

Background: The use of ureteroscopy in the management of urolithiasis is well established. Ureteral avulsion is a rare but challenging complication of the procedure. Postureteral injury strictures are a common result of such injuries and are typically managed with reconstructive surgery or endoscopically with polymer stent. This case represents the first effective management of ureteral avulsio...

Objective: To compare the effects of calculus removal through nephroscopy and holmium laser calculus removal through ureteroscopy on patients with concurrent urinary infection at one side of their upper ureteral calculi. Method: A total of 160 patients admitted to our hospital because of concurrent urinary infection at one side of their upper ureteral calculi were selected from March 2014 to Fe...

OBJECTIVE To verify if post-ureteroscopy (URS) stenting is still necessary as a routine strategy, or if some cases can be treated without. METHODS Between August 2004 and April 2005, 85 patients were admitted to the Urology Department at the Nephrology and Urology Center, Al-Thawra Hospital, Yemen with ureteric stones of different size and site. All were scheduled and treated by the ureterosc...
