PURPOSE The treatment of urinary tract stones in obese patients may differ from the treatment of non-obese patients and their success rate varies. Our objective was to compare ureteroscopic treatment outcomes of ureteral and renal stones, stratified for stone size and location, between overweight, obese and non-obese patients. MATERIALS AND METHODS Charts were reviewed for 500 consecutive pat...

We report our early experience with a new device for endoscopic stone disintegration: the Swiss lithoclast. This device was used to treat 200 patients with stones in kidney, ureter, and bladder. Its effectiveness was 100% when the stone could be approached irrespective of size or composition, and no complication was encountered. Prof. A. Kostakopoulos, Department of Urology, Sismanoglion Genera...

This case report presents the diagnostic and treatment procedures of stone removal from the kidney of a 67-year-old donor, the transplantation of the kidney to a 65-year-old recipient, and the postoperative course until the end of hospitalization. Computed tomography performed before collecting the organ showed a staghorn stone in the renal pelvis and lower calyces in the right donor kidney. Th...

In this paper we investigate the problem of \partializing" Stone spaces by \Sequence of Finite Posets" (SFP) domains. More specifically , we introduce a suitable subcategory SFP m of SFP which is naturally related to the special category of Stone spaces 2-Stone by the functor MAX, which associates to each object of SFP m the space of its maximal elements. The category SFP m is closed under limi...

Ureteroscopic lithotripsy using Swiss Lithoclast was performed in 411 cases from January 1996 to September 2007 in a single hospital. Medical records of 341 cases, in which Swiss Lithoclast was successfully applied, were available for this retrospective study. We used 9.5Fr and 10Fr Storz rigid ureteroscopes. A success was defined as being free of stone-related symptoms and residual stones larg...

Two patients with renal pelvic stone in a horseshoe kidney who underwent a percutaneous nephrolithotripsy (PNL) are presented. Case 1 was a 36-year-old man with a 20 x 12 mm right renal pelvic stone in a horseshoe kidney. Case 2 was a 47-year-old man who had been followed up at our clinic for a horseshoe kidney and was found to have a 15 x 10 mm left renal pelvic stone. We found that percutaneo...

OBJECTIVE To determine the safety and efficacy of ureteroscopic pneumatic lithotripsy (PL) for the clearance of ureteral calculi (UC). STUDY DESIGN Experimental study. PLACE AND DURATION OF STUDY Department of Urology, KRL Hospital, Islamabad, from March 2006 till December 2008. METHODOLOGY Ureteroscopic PL was performed on 104 patients with ureteric calculus measuring > 6 mm; using Swiss...

Percutaneous nephrolithotomy is generally considered the first choice for the treatment of large upper urinary tract stones. However, laparoscopic stone surgery with or without robotic assistance is a viable alternative especially in cases with aberrant anatomy such as ectopic or malrotated kidneys (1-3). A recent meta-analysis found several advantages of the laparoscopic approach, especially r...
