Background and Objectives: The combined use of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is employed for the treatment of peritoneal carcinomatosis (PC). To achieve optimal cytoreduction, there may be a need for extensive resection and subsequent reconstruction of urologic structures. This study was designed to evaluate the outcomes of urinary tract resection or repair performed in CRS/HIPEC in terms of operative and oncological outcomes. Materials and Methods: After institutional review board approval, data from 550 consecutive patients who underwent the CRS/HIPEC procedure from January 2007 to July 2018 at six university hospitals was retrieved from prospectively maintained databases. Data from patients who had a concomitant curative resection and reconstruction of the bladder, ureter, or kidney during the CRS/HIPEC procedure were analyzed retrospectively. Results: A total of 50 out of 550 patients had undergone resection with a repair of the urinary tract due to tumor invasion or iatrogenic injury. Postoperative (within 30 days) urologic complications were observed in 9 of the 50 patients. It was found that having a peritoneal cancer index (PCI) equal to or greater than 20 (p < 0.009) was the sole significant risk factor associated with the occurrence of early urinary complications. Survival time post CRS/HIPEC treatment did not significantly differ between patients with and without urologic complications (median overall survival: 23 vs. 27 months, p = 0.683). Conclusions: Despite urinary tract issues during CRS/HIPEC for PC, including a PCI over 20 and potential complications from resection or repair, the procedure still offers significant survival benefits.
