Objectives: To compare outcome of open ureterolithotomy versus semi-rigid ureteroscopy in management of large upper ureteric stones. Patients and Methods: Patients with large upper ureteric stones (≥2cm) who were managed by ureteroscopy (31 patients) or ureterolithotomy (31 patients) were included retrospectively from January 2012 to December 2014. Primary stone-free rate (SFR), secondary SFR (...

Objective: To determine the effect of diagnostic ureteroscopy on intravesical recurrence in patients with upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU). Methods: We conducted a retrospective analysis of 664 patients who were treated with RNU for UTUC from June 2000 to December 2011, excluding those who had concomitant/prior bladder tumors. Of the 664 patients, 8...

In the past several decades there has been a remarkable development of small-caliber, flexible ureteroscopes and various ancillary instruments for stone manipulation and retrieval. Percutaneous antegrade ureteroscopy can be substituted in select cases for retrograde ureteroscopy. We report a case of a 60-year-old man with severe ankylosis in both hip joints who was diagnosed with bilateral uret...

Over the last two decades there has been an increase in the incidence of kidney stone disease with a simultaneous rise in the use of ureteroscopy for its management [1]. Flexible ureteroscopy training is variable and still largely dependent on high fidelity models and virtual reality (VR) simulation, both of which are expensive and not readily available in many parts of the world. There is also...

PURPOSE Same-session ureteroscopy for bilateral urinary calculi would potentially reduce costs and the need for a second anesthetic compared with staged procedures. We sought to establish the safety and efficacy of same-session bilateral ureteroscopy relative to procedures for staged bilateral and multiple unilateral calculi in the context of contemporary instrumentation. PATIENTS AND METHODS...

OBJECTIVE To study the safety and efficacy of ureteroscopy as an out-patient procedure. DESIGN Retrospective study. SETTING Teaching hospital, Singapore. SUBJECTS AND METHODS Operating facilities for out-patient ureteroscopy were introduced in late 1998. A retrospective review of all patients undergoing ureteroscopy from March 1999 to December 2000 was conducted. Clinical records were rev...

OBJECTIVES To correlate urologists' impressions of the tumor grade of upper tract tumors at ureteroscopy with the histologic findings after biopsy or resection. METHODS A retrospective review of all patients who underwent diagnostic or therapeutic ureteroscopy for upper tract transitional cell carcinoma (TCC) between 1992 and 2002 was performed. Only patients who had proven TCC with a descrip...

OBJECTIVES To provide an insight into the current status of semi-rigid and flexible ureteroscopy, following new curricula for training methods, including training with models, virtual reality and active mentoring. METHODS We systematically reviewed previous reports, including articles in English identified using the following strategy: ('ureteroscopy'[Mesh]) or ('urolithiasis'[Mesh]) AND ('ed...

Our "tips and tricks" focuses on all aspects of upper tract endourology and we hope these will be of use to all trainees and consultants who perform ureteroscopy. We report an "expert consensus view" from experienced endourological surgeons, on all aspects of advanced ureteroscopic techniques, with a particular focus on avoiding and getting out of trouble while performing ureteroscopy. In this ...

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 ...
