Modified Ileal Conduit for Pelvic Lipomatosis: Technique Description and Outcome.

INTRODUCTION

The aim of this study was to present the surgical technique and clinical outcomes of modified ileal conduit for pelvic lipomatosis (PL).

METHODS

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.

RESULTS

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 (p = 0.006 and p = 0.024). The postoperative 3-month and 1-year estimated glomerular filtration rate values were significantly increased compared with those before operation (p = 0.0002 and p = 0.018). The separation value of left renal pelvis collection system after operation was significantly reduced compared with preoperative evaluation (p = 0.023 at 3 months and p = 0.042 at 1 year) and so was the right side (p = 0.019 and p = 0.023).

CONCLUSION

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.
