Methods: A retrospective analysis of all pyeloplasties done for children of weight under 20 kg was carried out. Indwelling stents were the standard of care. However, in smaller children, a ureteric catheter was placed as splint. Patient demographics, duration of surgery, length of hospital stay, postoperative complications and re-intervention rates were collected. Success was defined as resolution of symptoms or absence of hydronephrosis during the follow-up Results: Atotal of 157 pyeloplasties was performed in children with a weight less than 20 kg between 2006 and 2018. Half of them were open pyeloplasty (OP, n = 78) procedures while laparoscopic pyeloplasty (LP, n = 52) and robotic pyeloplasty (RP, n = 27) made up the other half. Over the mean follow-up of 16.3 months, the success rates were comparable (98.7% vs. 96.2% vs. 96.3%) in the OP, LP and RP groups respectively. Mean operative time was significantly longer by 35 mins in both LP and RP groups when comparing with OP. Hospitalisation was significantly shorter in the minimally invasive groups (4 days) compared to the OP group (7days). Postoperative complications were not significantly different. Conclusions: In our series, LP and RP had equivalent outcomes to OP with a shorter hospital stay. The minimally invasive approach in children less than 20 kg of weight should be reserved to centres with expertise as the benefit is currently small. Open pyeloplasty remains the gold standard in these small children. Comparison of Rezum versus Urolift in the Management of Benign Prostatic Hypertrophy P. Alilio, N. Russo, J. Gupta Lehigh Valley Health Network, Allentown, PA, USA Introduction and Objective: Benign prostatic hypertrophy (BPH) affects roughly 50% men over the age of 50 and causes a variety of lower urinary tract symptoms (LUTS) which can significantly influence quality of life. Two methods of BPH treatment, Rezum and Urolift, have emerged as less invasive alternatives to TURP. Our objective was to assess the outcomes of Urolift and Rezum at the Lehigh Valley Health Network. The outcomes will include the international prostate symptom score, post-void residuals, prostate size and reoperation rates. Methods: Retrospective review identified patients who underwent either Urolift or Rezum between January 1, 2019 and Apr 30, 2020. Self-reported American Urologic Association Symptom Index (AUASI) score, Quality of Life (QOL) score as well as post-void residuals (PVR), urinary flow rate (Qmax), number of follow-up phone calls, reoperation occurrence, retention and PSA variation were collected. Chi-square and Fisher’s exact tests were used to compare categorical variables. Results: Seventy-three and fifteen patients underwent Rezum and Urolift, respectively. Thirty-nine (53%) and 6 (40%) of patients who underwent RezumandUrolift, respectively, demonstrated a reduction in theAUASI score over the course of 6 months. In the Rezum cohort, Qmax increased from an average 9.68±6.2mL/second (sec) pre-procedure to 12.11±7.2mL/sec at the three month follow up, and PVR decreased from an average 71.09±120mL to 61.34±131.93mL. In the Urolift cohort, the Qmax average decreased from 9.13±5.2mL/sec pre-procedure to 7.32±3.04mL/sec at the 6 month follow up, PVR decreased from an average 129.75±183.4mL to 81.14±79.4mL. Conclusions: Our study demonstrates a decrease in overall self-reported and clinical symptoms from BPH with the Rezum procedure. The Urolift procedure demonstrated some reduction to LUTS, but a further study expanding the collection period is desired. MP3-05 20
