Publication Comparison of Outcomes of Open versus Laparoscopic Living Donor Nephrectomy in Nepal(Institute of Medicine, 2020) Sigdel, Prem R; Gnyawali, Diwas; Rai, Bipendra D K; Dhital, Pawan; Parajuli, Purushottam; Chudal, Sampanna; Dhakal, Niraj; Pradhan, Manish; Poudyal, Sujeet; Chapagain, Suman; Luitel, Bhoj R; Chalise, Pawan R; Sharma, Uttam K; Gyawali, Prem RABSTRACT Introduction: Laparoscopic 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 the experience and outcomes of laparoscopic donor nephrectomy in Nepal. The study was done to compare the outcomes among donors undergoing open and laparoscopic nephrectomies, and to compare the graft related outcomes between the two groups receiving these kidneys. Methods: In 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 of hospital stay. Data on early graft function and complications in recipients till 30th post-operative day were compared. Results: There 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. Conclusion: Laparoscopic donor nephrectomy is feasible in Nepal and associated with acceptable morbidity and graft function when compared to ODN.

Studies have shown computed tomography measured renal volume can also be used. Our main objective was to assess the accuracy of volume based estimated GFR (vGFR) with diethylene triamine penta acetic acid (DTPA) measured GFR in living kidney donors. Methods: An observational analytical study was conducted from July 2018 to June 2019 in Department of Urology and Kidney Transplant Surgery and Department of Radiodiagnosis in Tribhuvan University Teaching Hospital where a total of 38 eligible potential donors were evaluated and serum creatinine level, computed tomography with contrast and DTPA renogram were used to measure GFR and differential function. Results: The mean age of the donors were 42.8±10.9 years with 70% of donors being females. Renal volume was not statistically different between male and female donors. There was moderate correlation between volume based and DTPA based GFR (r=0.76) and differential function (r=0.71). Compared to creatinine, volume based GFR estimate showed better correlation to DTPA renogram. There was no significant difference in differential function estimated by DTPA and volume based estimates (p = 0.96). The upper and lower limit of agreement between the volume based and DTPA based differential function was –4.7 and 4.6 respectively. Conclusion: GFR measurement by CT volume overestimates total GFR compared to DTPA renogram but it has better correlation than creatinine based estimates. It can be used to estimate the differential function of the donor kidney.

It complicates the treatment of infections like urinary tract infections, leading to treatment failure, extended hospital stays, and increased healthcare costs. Empirical antibiotic therapy, guided by local resistance patterns, is crucial for patient outcomes and infection prevention. This study analyzes urine cultures from TU-Teaching Hospital from January to December 2024 to investigate the prevalence and antimicrobial susceptibility of multidrug-resistant uropathogens. Methods: This was a retrospective, observational hospital-based study conducted in a tertiary care center after obtaining the ethical approval from Institutional Review Committee (IRC), (Approval reference: 470 (6-11) E2). All samples tested fromJanuary 1, 2024, to December 31, 2024 the period included in the study. Data were collected from the Electronic health records of the Microbiology department and analyzed using Microsoft Excel 16.0.0 and SPSS 30.0.0 software to determine the urine culture positivity rate, the prevalence of multidrug-resistant uropathogens, and their antimicrobial susceptibility patterns with a specific focus on resistance to commonly prescribed antibiotics. Results: A total of 25,315 urine samples were collected for urine culture and sensitivity testing during the study period. Significant bacterial growth was seen in 4,557 (18%). Multidrug resistance was seen in 3,448 (75.66%). The most frequently isolated organisms were Escherichia coli 1724 (50%), Klebsiella 154 (17.7%). E. coli, Klebsiella, Enterococcus, Citrobacter, Pseudomonas, and Acinetobacter showed resistance to Ceftriaxone (74.61–92.20%), Amoxycillin+Clavulanate (67.58–97%), and Nitrofurantoin (52.29–89.55%) across selectively tested isolates. Conclusions: Urine samples demonstrated a high prevalence of multidrug resistance to routinely prescribed antibiotics, even among second-line parenterally administered antibiotics. Only costly third-line antibiotics exhibited low resistance.
