The Urological Association of Asia, consisting of 25 member associations and one affiliated member since its foundation in 1990, has planned to develop Asian guidelines for all urological fields. The field of stone diseases is the third of its guideline projects. Because of the different climates, and social, economic and ethnic environments, the clinical practice for urinary stone diseases widely varies among the Asian countries. The committee members of the Urological Association of Asia on the clinical guidelines for urinary stone disease carried out a surveillance study to better understand the diversity of the treatment strategy among different regions and subsequent systematic literature review through PubMed and MEDLINE database between 1966 and 2017. Levels of evidence and grades of recommendation for each management were decided according to the relevant strategy. Each clinical question and answer were thoroughly reviewed and discussed by all committee members and their colleagues, with suggestions from expert representatives of the American Urological Association and European Association of Urology. However, we focused on the pragmatic care of patients and our own evidence throughout Asia, which included recent surgical trends, such as miniaturized percutaneous nephrolithotomy and endoscopic combined intrarenal surgery. This guideline covers all fields of stone diseases, from etiology to recurrence prevention. Here, we present a short summary of the first version of the guideline – consisting 43 clinical questions – and overview its key practical issues.

Uropathogens in many Asian countries had high resistance to broad-spectrum antibiotics. Knowledge of regional and local resistance data and prudent use of antibiotics are important for proper management of UTI in Asian countries.

Background Renal tumor is the 13th most common malignancy in the world and more than 90% of renal tumors are renal cell carcinomas. As there is no data available on renal cell carcinoma in Nepal, hence this study was undertaken to analyze the patterns of renal cell carcinoma in patients with renal mass at a tertiary level hospital in Nepal. Objectives To analyze the patterns of renal cell carcinoma in patients with renal mass at a tertiary level hospital in Nepal. Methods The case records of 50 consecutive patients with renal cell carcinoma presenting at the Tribhuvan University Teaching Hospital, Kathmandu from July 2006 to June 2011 were retrospectively evaluated for presenting symptoms, physical finding, investigation and histopathology report. Results Out of 50 patients, 64% were male and 36% were female. The age ranged between 11 to 78 years (mean ± SD: 55 ± 15 years). Fifty four percent of patients were smokers. Incidentally tumor was detected in 40% cases by ultrasonography and the typical triad was present in only 4%. The tumor was occupying upper pole in 40% of cases. The tumor size ranged from 3 to 15 cm (mean ± SD: 7.3 ± 2.9 cm). Histopathologically, 76% of the patient had organ confined renal cell carcinoma (T1-2 N0 M0). Clear cell was the most common type seen in 86%. Fuhrman’s nuclear grade 2 was found in 50%. ConclusionMany of the renal cell carcinoma are detected incidentally, at an early stage and are of clear cell subtype.DOI: http://dx.doi.org/10.3126/kumj.v9i3.6302 Kathmandu Univ Med J 2011;9(3):185-8

Introduction. Urolithiasis is one of the common disorder with which about 1/5th is found in the ureter, of which 2/3rd is seen in the lower ureter. Medical expulsive therapy is one of the routine modalities of treatment which uses various drugs acting on the ureter smooth muscle by different mechanism. We aim to compare the efficacy of combination vs. single drug. Methods. This randomized controlled trial was done in 176 consecutive patients over a period of six months (March 2019 to August 2019) in Department of Urology and Kidney Transplant Surgery, Tribhuvan University Teaching. Participants were divided into two groups (Group A, tamsulosin plus tadalafil, and Group B, tamsulosin) from computer-generated random numbers. Therapy was continued for a maximum of 3 weeks. Stone expulsion rate, time to stone expulsion, analgesic use, number of colic and emergency room visits for pain, early intervention, and adverse effects of drugs were recorded. Results. Among 176 patients who were enrolled in study, 7 were lost to follow-up, and 5 people required immediate intervention. There was a significant higher stone passage rate in group A than group B (64 vs. 50; P=0.025) and shorter expulsion time (1.66 vs. 2.32 weeks P=0.001) and less number of emergency room visits and colic episodes. No significant side effects were noted during study. Conclusion. Tamsulosin plus Tadalafil is more effective than tamsulosin with early passage of stone and decreased number of colic episodes and emergency visits without significant side effects for lower ureteric calculi of 5 mm to 10 mm.

Introduction: Ureteral stent placement is an increasingly common procedure in urological practice.They are used for both prevention and treatment of ureteral obstruction. Despite improved design and materials, many patients still develop stent-related symptoms which commonly affect quality of life and sometimes necessitate early removal. Tamsulosin improves stent-related symptoms and quality of life, and can be applied in routine clinical practice. In the present study, the effect of Tamsulosin in improving double-J stent-related symptoms and quality of life following ureteral stent placement was studied.Methods: This RCT was carried out in the Department of Surgery, Tribhuvan University Teaching Hospital, Kathmandu, Nepal from February 2015 to January 2016. Forty six patients were included in the study and randomized into Tamsulosin(T) group and Control(C) group each having 23 patients. In addition to standard postoperative care, Tamsulosin group received 0.4mg Tamsulosin daily and Paraceramol on demand and control group received only Paracetamol. Stent related symptoms and quality of life was assessed by IPSS at discharge (day2) and at the time of DJ stent removal (2 weeks). Pain was evaluated by VAS and analgesic requirement was documented. Data were analysed using SPSS 20, chi-square test and Student’s t- test was used. A p-value of <0.05 was considered significant.Results: Mean age in Tamsulosin group was 37.96±12.98 and Control group 36.43± 10.99(p=0.67).There was no significant difference in IPSS(p=0.141), QoL index (p=0.089) and VAS (p=0.59) in the two groups at the time of discharge.At the time of DJ stent removal, IPSS (p<0.001), QoL index (p<0.001), VAS (p=0.004) and analgesic needed (p<0.001) was significantly lower in T group than in C group.Conclusion: Tamsulosin lowers stent related symptoms, pain and improves quality of life in patients with indwelling DJ stent though the effect is not immediate.
