PURPOSE To report the outcomes of laparoscopic surgery combined with endourological assistance for the treatment of renal stones in patients with associated anomalies of the urinary tract. To discuss the role of laparoscopy in kidney stone disease. MATERIALS AND METHODS Thirteen patients with renal stones and concomitant urinary anomalies underwent laparoscopic stone surgery combined with anc...

BACKGROUND Ipsilateral asymptomatic renal stone associated with symptomatic ureteral stone is not a rare event, and the recommended treatment policy was not declared clearly. This study was conducted to compare the outcomes of simultaneous retrograde intrarenal surgery (RIRS) and ureteroscopy to ureteroscopy alone for this clinical event. METHODS 415 patients with symptomatic ureteral stone a...

Urinary stone formation is one of the oldest and most widespread diseases known to man. The disease has a multifactorial etiology that includes anatomic, environmental, genetic, infectious, metabolic, nutritional, importantly socio-economic factors. It caused by biochemical imbalance in urine between stone-forming inhibitors promotors process as lithogenesis. mechanisms underlying development u...

INTRODUCTION We intended to evaluate the feasibility and effectiveness of the simultaneous rigid and flexible ureteroscopic treatment of symptomatic ureteral and ipsilateral small simultaneous calyceal stones. Outcomes of combined therapy were compared with monotherapy alone. MATERIAL AND METHODS In this retrospective study, group 1 consisted of 45 patients with middle or lower ureteral and i...

This investigation highlights the use of infrared microspectroscopy for the morphological analysis of urinary stones. The research presented here has utilized the reXectance mode of an infrared microscope for use in creating chemically speciWc maps of cross-sectioned renal calculi surfaces, precisely showing the placement of renal stone components in a calculus sample. The method has been appli...

In order to promote stone passage in renal colic, we must first understand normal ureteral activity and how this is affected by the presence of a stone. Measuring normal ureteral activity in humans is difficult without the use of invasive methods or techniques which in themselves may affect peristalsis. Monitoring the activity during confirmed renal colic is even more difficult and virtually im...

AIM Despite the extensive experience with minimal invasive stone therapy, there are still different views on the ideal management of renal stones. MATERIALS AND METHODS Analysis of the literature includes more than 14,000 patients. We have compared these data with long-term results of two major stone centers in Germany. The results have been compared concerning the anatomical kidney situation...

A male patient, born in 1990, first presented with a kidney stone when he was 10 years old, but the stone had passed spontaneously, and no further testing was done at that time. At the age of 20, he presented with a second episode of renal colic. Proteinuria and microscopic haematuria were also noticed, for which he was referred to a nephrologist. On examination, he was a lean young man with no...

We treated 97 patients with staghorn calculi by ESWL monotherapy using a Lithostar Lithotriptor (Siemens) between January 1989 and December 1996. Seventeen patients (18 renal units) out of 45 patients (47 renal units) who could be followed up for more than 12 months after ESWL had no stones on radiographs at 3 months after the treatment. The actuarial non-recurrence (or stone-free) rate was 88....

OBJECTIVES To investigate the situations in which ureteral double-J stent should be used after retrograde intrarenal surgery (RIRS). PATIENTS AND METHODS Patients with no ureteral double-J stent after RIRS constituted Group 1, and those with double- J stent after RIRS constituted Group 2. Patients' age and gender, renal stone characteristics (location and dimension), stone-free status, VAS sc...
