IntroductionLaparoscopic donor nephrectomy is the gold standard for kidney retrieval in live donors. Until recently,donor nephrectomies were performed only by open technique in Nepal. There is no information on theexperience and outcomes of laparoscopic donor nephrectomy in Nepal. The study was done to comparethe outcomes among donors undergoing open and laparoscopic nephrectomies, and to compare the graft related outcomes between the two groups receiving these kidneys.MethodsIn this retrospective study, 44 kidney donors from March 2019 to October 2019 were analyzed. Donors were divided into 2 groups: open donor nephrectomy (ODN) and laparoscopic donor nephrectomy (LDN).Parameters for analysis included demographic data, warm ischemia time, surgery time and length ofhospital stay. Data on early graft function and complications in recipients till 30th post-operative day were compared.ResultsThere were 22 donors each in the ODN and LDN groups. Baseline characteristics of the donors were comparable between two groups. Mean surgery duration (183.55±43.31 minutes vs 117.73±18.75 minutes) and first warm ischemia time (11.22±4.34 minutes vs 2.3±0.8 minutes) was significantly high in LDN. Hemoglobin drop, post-operative complications in donors, creatinine of donors at discharge, mean hospital stay, graft function at one month and complications in recipients were comparable among ODN and LDN. Pain score in 1st post-operative day was comparable between two groups, however, pain was significantly less in second post-operative day in LDN.ConclusionLaparoscopic donor nephrectomy is feasible in Nepal and associated with acceptable morbidity and graft function when compared to ODN.Keywords: Laparoscopic donor nephrectomy, open donor nephrectomy, renal transplantation

Renal metastasis from osteosarcoma is a rare entity, and tumour thrombus is even rarer. To date, only 15 cases of osteosarcoma with tumour thrombus have been reported in the literature. We present a case of an 18-year-old female diagnosed as having right distal femur osteosarcoma, later presenting with renal osteosarcoma with IVC thrombus.

PURPOSE This study was aimed to compare lymphatic complications of bipolar vessel sealing system with silk ligation of lymphatic vessels among renal transplant recipients. METHODS This was a prospective randomized controlled trial done among 68 patients undergoing renal transplantation in Tribhuvan University Teaching Hospital. They were randomly assigned to either silk ligation or Enseal bipolar vessel sealing lymphatic dissection. Postoperative drain volume and duration of drain placement were measured in all patients. Ultrasound was used to find lymphocele formation in six and 12 weeks. RESULTS Total of 30 patients in silk ligation group and 28 patients in bipolar vessel sealing group were analyzed. The baseline characteristics of the patients in each group were similar. Overall, lymphatic complications (either lymphorrhea or lymphocele formation) were in 16 cases (27.58%), 7 (25%) in the bipolar group, and 9 (30%) in the silk ligation group (p = 0.67). A total of 13 patients (22.41%) had lymphorrhea, 6 (21.4%) patients in the bipolar group, and 7 (23.3%) patients in the silk ligation group. Median drain volume was 415 ml (Q1 275 ml, Q3 675 ml) in the bipolar group and 542 ml (Q1 290, Q3 775) in silk group (p = 0.72). Median drain removal day was 5 in each bipolar and silk group with Q1 and Q3 being 5 days in each arm (p = 0.95). A total of five patients (8.62%) developed symptomatic lymphocele, two (7.1%) in the bipolar group, and three (10%) in the silk ligation group, but the difference was not statistically significant. In univariate analysis, double renal arteries in the donor's kidney (p = 0.03) and graft rejection (p = 0.04) were risk factors for the development of lymphatic complications. However, in multivariable analysis, these factors were not statistically significant. CONCLUSIONS This study did not find any significant differences in lymphatic complications between bipolar vessel sealing system and silk ligation. However, large sample multi-centric studies should be done to add evidences on lymphatic complications differences between these two techniques.

To define the clinical and pathological patterns of urinary bladder carcinoma from the University Hospital of Nepal. This is a retrospective analytical study. Patients with bladder mass who underwent surgery over 1 year and who had data record were included in the study. Demographic profile, type of surgery, findings on clinical examination, cystoscopy findings, histopathological report, tumor stage, and post-surgery adjuvant therapy were analyzed. Out of 86 patients who underwent transurethral resection of bladder tumor, 77 patients had biopsy-proven malignant bladder tumor. Urothelial cancer was present in 96.1%. Male were 78.6%. The mean age of diagnosis was 65.5 ± 11.8 years. Non-muscle-invasive bladder cancer (NMIBC) was 3.7 times more common than muscle-invasive bladder cancer (MIBC). High-grade tumors (58.6%) were more common than low grade (41.4%). The detrusor muscle was present inthe biopsy specimen of 48 patients (64%). Re-TURBT within 2–6 weeks was considered based on histopathology reports for about half of the patients (45.3%). Upstaging and upgrading of the tumor was present in 5.8 and 5.8% of the patients, respectively. Residual tumor without upstaging and upgrading was present in 23.5%. One patient (1.3%) had Clavien–Dindo grade 1, three (4%) patients had grade 2 and two patients (2.7%) had grade 3b. In the present study, patients with bladder cancer are younger than reported in other studies. Smokers are strongly predisposed. The histological pattern is similar to the Western and Asian populations. NMIBC and MIBC occur in proportion to that described as in other studies. We had a lower rate of recurrence, upstaging and upgrading. We had a lesser rate of acceptance for radical cystectomy in our patients.

Hydatid disease in developing countries like Nepal is not uncommon but isolated renal involvement without liver and lung hydatid is rarely described in literature. It may create diagnostic dilemma at times. We describe a 22-year-old female with isolated renal hydatid disease managed with nephron sparing surgery (NSS).

Gestational choriocarcinoma with kidney and lung metastases with delayed presentation after term pregnancy is rare event and not described frequently in literature. We describe a rare case of 24-year-old female with hematuria after 3 years of term delivery. Management includes chemotherapy and even renal embolization in case of life threatening hematuria.

Highlights • Atrial fibrillation is associated with peripheral embolism. • Renal artery embolism is reported in rare instances. • Clinical suspicion in high risk patient and urgent treatment is key to success., Introduction Renal artery embolism is uncommon cause of flank or back pain. Of all embolic episodes in patients with atrial fibrillation, 2–4% are renal artery embolism. Early thrombolysis within 90 min has favorable renal outcome. Long term anticoagulation can prevent recurrent embolic episodes. Two different embolic phenomenon within short span in same patient is not described in literature. Presentation of case We describe fifty-year-old female with rheumatic heart disease with atrial fibrillation presented as renal segmental artery emboli with popliteal artery emboli within seven-day interval. Discussion Embolic phenomenon is well known in atrial fibrillation. High index of suspicion in patient with risk factors of thromboembolism with appropriate use of contrast enhanced computed tomography can help early diagnosis. Renal artery embolism is managed with anticoagulation or thrombolysis based on duration of presentation. Peripheral artery embolism can be diagnosed with Doppler ultrasonography. Thrombus can be removed with endovascular procedure or open surgical technique. Holistic patient management includes cardiac workup and treatment of factors predisposing to embolization. Conclusion Early identification and urgent treatment is key to the management of embolic episode in patient with atrial fibrillation. Long term prophylaxis can prevent further episodes.

INTRODUCTION Abdominal trauma is one of the preventable causes of death in polytrauma patients. Decision and timing of laparotomy is a major challenge. Rate of nontherapeutic laparotomy is still high. Laparoscopy can avoid nontherapeutic laparotomy and also provide a reliable and accurate diagnosis of injury. MATERIALS AND METHODS This ambispective observational study was conducted in the division of Trauma Surgery and Critical Care, JPN Apex Trauma Centre, All India Institute Medical Sciences, New Delhi. Retrospective analysis of prospectively maintained data of cases from January 1, 2008 through April 30, 2013 and prospective analysis of cases from May 1, 2013 through March 31, 2015 was done using appropriate measures. Hemodynamically stable or responders fulfilling inclusion criteria were included. Selected patients underwent the laparoscopic procedure and if required converted to laparotomy. RESULTS Of the 3610 patients of abdominal trauma, laparotomy was done in 1666 (46.14%) patients and laparoscopy was done in 119 (3.29%) patients. Rate of reduction of nontherapeutic laparotomy in patients with abdominal trauma using diagnostic laparoscopy was 55.4%. However laparotomy could be avoided in 59.7%. Laparoscopy was 100% accurate in identifying injuries in our study. No injuries were missed in these patients. Fever and wound infection were significantly higher in laparotomy group. Chest infection and sepsis were also higher in laparotomy group but the difference was not statistically significant. Median length of hospital stay in laparoscopy group was 4 days (range: 1 to 28 d) and in laparotomy group was 9.5 days (range: 2 to 55 d) with P-value of 0.001. CONCLUSIONS Laparoscopy has a role in management of hemodynamically stable patients with suspected abdominal injury to prevent nontherapeutic laparotomies, and thereby decreasing postoperative complications.

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 and importance Adrenal schwannomas are extremely rare tumors often misdiagnosed. The patients are usually asymptomatic while some present with non-specific abdominal pain. Only a few cases are reported to date. Case presentation We here present a case of a 55-year-old Nepalese man presented with nonspecific abdominal pain at our Outpatient Department (OPD) found to have mass on ultrasonography of abdomen. On further investigation with Contrast Enhanced Computerized Tomography (CECT) of the abdomen and pelvis, a well-defined heterogeneous adrenal mass of size (7.8 ∗ 8.3 ∗ 6) cm with foci of calcification was seen in the left retroperitoneum. The intraoperative finding of adrenal mass and histopathology of resected mass was suggestive of schwannoma arising from the adrenal gland which was further confirmed by immunohistochemistry. Clinical discussion Adrenal schwannoma can mimic tumors like pheochromocytoma, adrenal adenoma, cortical carcinoma, neuroblastoma, and other masses. Only 1–3% of schwannomas are retroperitoneal. Radiological findings of this tumor are non-suggestive. The histological section shows spindle cells with Antoni A and Antoni B regions while positive staining of S-100 protein in Immunohistochemistry. Conclusion The diagnosis of adrenal schwannoma in the retroperitoneum is often challenging. The treatment of choice is surgical resection with a good prognosis., Highlights • Adrenal schwannomas are extremely rare tumors. • These tumors are mostly found incidentally and often asymptomatic. • Complete surgical resection of the tumor is a must for good prognosis.
