Modified Ileal Conduit for Pelvic Lipomatosis: Technique Description and Outcome

Abstract

<b><i>Introduction:</i></b> The aim of this study was to present the surgical technique and clinical outcomes of modified ileal conduit for pelvic lipomatosis (PL). <b><i>Methods:</i></b> From 2020 to 2022, we prospectively enrolled 9 patients with PL undergoing modified ileal conduit. The patient characteristics, perioperative variables, and follow-up outcomes as well as the description of surgical technique were reported. <b><i>Results:</i></b> All 9 patients successfully completed the operation. Two patients had perioperative complications of Clavien-Dindo grade I. The mean operation time and bleeding volumes were 253 ± 51.4 min and 238.9 ± 196.9 mL, with a mean postoperative follow-up time of 13.0 ± 5.6 months. The postoperative 3-month and 1-year creatinine values were significantly decreased versus the preoperative (<i>p</i> = 0.006 and <i>p</i> = 0.024). The postoperative 3-month and 1-year estimated glomerular filtration rate values were significantly increased compared with those before operation (<i>p</i> = 0.0002 and <i>p</i> = 0.018). The separation value of left renal pelvis collection system after operation was significantly reduced compared with preoperative evaluation (<i>p</i> = 0.023 at 3 months and <i>p</i> = 0.042 at 1 year) and so was the right side (<i>p</i> = 0.019 and <i>p</i> = 0.023). <b><i>Conclusion:</i></b> Modified ileal conduit is safe and feasible for PL. A large sample cohort with long-term follow-up is needed to evaluate the clinical outcomes of PL.
