“…The prevalence of stone disease is increasing with increasing annual expenditure. 2 Socioeconomic status, environmental factors, genetic predisposition and certain metabolic disorders are some of the known risk factors of this disease. 3 Open surgical procedures for the treatment of ureteric stones have gradually disappeared in the last 30 years due to the emergence of increasingly efficacious minimally invasive techniques such as ESWL and ureteroscopy.…”

Introduction: With advent of URSL (ureterorenoscopy and lithotripsy) and other minimally invasive technique viz; SWL (shock wave lithotripsy), PCNL (percutaneous nephrolithotomy), the urinary stones management has taken a giant leap to serve mankind. The aim of this study is to review a wide series of ureteral stones in which ureteroscopy combined with endoscopic lithotripsy was chosen as the first approach for the treatment of ureteral calculi and to study its diagnostic efficacy. Methods: This is a retrospective study that was carried out in Patan Hospital from Feburary 2010 to Jan 2013. In all cases preoperatively intravenous urography, and a plain film of the urinary tract was taken before the procedure. The operations were carried out with the patient under general anesthesia. Rigid ureteroscopes and the pneumatic lithotripter were used. The fragments were extracted with forceps or baskets assisted with saline flush. Results: We analyzed the result of URSL done in our hospital for variety of urology problem. We found age group 20-40, being the most common group to develop urinary calculus. Most of our patient had single stone of size >5mm. Upper ureter, mid ureter and distal ureter comprises of 4, 30 and 56 stone respectively. Our success rate of URS insertion is 96%(96/100) with complete stone fragmentation with expulsion of the fragments occurred in 97.8%(88/90). Our major perioperative complication were 3% without mortality. Conclusion: URS is useful for diagnostic purpose & URSL is safe and treatment of choice for mid and lower ureteic calculus

The classic "infection stone" struvite is formed as a result of metabolic activity of urease-positive bacteria from alkaline urine with pH-values above 7.5. Due to improved infection diagnostics and antibiotic therapy, the occurrence of infection-related urinary stones in the western industrialized world decreases, despite the generally increasing prevalence rates of urolithiasis in these societies. Struvite is often associated with other mineral phases. These accessory mineral phases could indicate other, non-infection-related causes of urinary stone formation. Thus, mineral analysis is always recommended. Struvite stones as well as struvite encrustations on urinary tract implants are characterized by rapid growth. The rapid growth-related embedding of urease-positive bacteria in the crystalline material makes the urinary stone a persistent source of recurrent urinary tract infections. According to the German Society of Urology guidelines on urolithiasis, a patient with the diagnosis "infection stone" should be assigned to the "high-risk" patient group. Complete stone and debris removal, as well as a special metaphylaxis strategy are required to initiate successful stone therapy.
