Publication Assessment of Volume Status Using Body Composition Monitor for Blood Pressure Control in Patients Undergoing Maintenance Hemodialysis: A Randomized Controlled Trial(Institute of Medicine, 2023) Dhakal, Niraj; Sapkota, Nisha K; Sigdel, Mahesh RABSTRACT Introduction: Optimal fluid balance and blood pressure control have been shown to improve outcomes in hemodialysis population. We investigated the effectiveness of body composition monitor (BCM) to target dry weight in maintenance hemodialysis (MHD) patients for blood pressure (BP) control and intradialytic adverse events. Methods: A total of 61 consenting adults under MHD were randomly allocated into either BCM group or Clinical Method group. Target dry weight was set every 4-weekly based on BCM report or clinical assessment; dry weight was adjusted with 200-500 ml/session reduction or increment of ultrafiltration in addition to interdialytic weight gain. Outcomes were analyzed in terms of BP control, anti-hypertensive medicine score, and intradialytic adverse events. Results: During 12 weeks of study period, systolic blood pressure (p<0.001), diastolic blood pressure (p=0.01) and mean arterial pressure (p<0.001) significantly decreased from baseline in BCM group but there were no significant changes in Clinical Method group. Lower blood pressure was achieved in BCM group as compared to Clinical Method group. There was a significant decrease from baseline in anti-hypertensive medicine score in the BCM group (p<0.001) but not in the clinical method group (p=0.34). There were significantly fewer events of cramps in the BCM group as compared to the Clinical Method group (p=0.04). Conclusion: BCM guided volume management in MHD patients was more effective than volume management based on clinical judgment only in controlling blood pressure and decreasing anti-hypertensive medicine burden and intradialytic cramps.

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.

We aimed to study the demographics, prevalence, clinical presentation, and outcome of TRAS. Methods: We retrospectively reviewed medical records of all living donor kidney transplant recipients at Tribhuvan University Teaching Hospital from August 2008 to May 2021. Cases diagnosed with TRAS by ultrasound Doppler and/or renal CT angiogram were included. Data on demographics, clinical presentation, management, and outcomes were collected and analyzed. Among patients who underwent revascularization, pre and post-procedure creatinine, blood pressure (BP), and antihypertensive medicine burden were compared. Results: Among 620 living donor kidney transplantation, TRAS was present in 17 recipients (Male:Female = 16:1) (2.6%); mean age was 35.47±12.71 years. The median duration at diagnosis was one-month post-transplant (range: 5 days-9 months). The most common clinical features of TRAS were graft dysfunction and uncontrolled hypertension. Diagnosis of TRAS was confirmed with CT angiography in 13 patients. Ten patients underwent revascularization. Pre and post-revascularization mean serum creatinine was 356±210.49 μmol/L and 122.8±30.48 μmol/L (p=0.007) respectively, mean systolic BP was 200±12.47 mmHg and 133±13.38 mmHg (p=0.005) respectively and mean diastolic BP was 105±15.09 mmHg and 80±9.43 mmHg(p=0.005) respectively. Significant reduction in anti-hypertensive pill burden was achieved. Conclusion: Prevalence of TRAS was 2.6%. Most cases presented early with hypertension and graft dysfunction. Revascularization of significant stenosis had a favorable outcome in terms of BP control, antihypertensive pill burden, and preservation of renal function.
