Combined Open Prostatectomy and Kidney Surgery: Feasibility and 12-Month Outcome

Purpose

There are only a few case reports and case series that investigated combined laparoscopic or robotic surgery for simultaneous prostate and kidney cancer. In this study, we want to close a gap in existing research to assess the feasibility and oncological outcome of combined open prostatectomy and kidney surgery.

Methods

We retrospectively analyzed patients who underwent a combined open prostatectomy and either a partial or complete nephrectomy from 2013 to 2020. Descriptive statistics were used to assess perioperative parameters and the 12-month functional and oncological outcomes after combined surgery.

Results

We identified 10 patients undergoing combined open surgery. Partial nephrectomy was performed in 4, radical nephrectomy in 6 patients. For prostate cancer, histopathological analysis showed a tumor stage ≥ pT2c in all 10 patients. For renal tumors, histopathological analysis showed clear cell renal cell carcinoma in 8 patients and oncocytoma in 2 patients. Operating time was 177 ± 36 minutes. Two perioperative complications (Clavien 2a and 3) were observed. Three months postoperatively, the International Index of Erectile Function (IIEF-5) score was 5.6 ± 5.9, the ICIQ-SF score was 7.3 ± 5.6 and were using 1.9 ± 2.2 pads per day. This improved after 12 months postoperatively, as patients had an IIEF-5 score of 6.33 ± 6.5, an ICIQ-SF score of 4.4 ± 5.7 and were using pads 0.9 ± 1.7 per day.

Conclusion

In this study, we showed that open surgery is a safe and valid approach for combined prostatectomy and renal surgery with acceptable complications and oncological outcomes. The combined open approach could be a good alternative to combined laparoscopic/robotic surgery in this field, especially to treat patients with advanced renal tumors or previous abdominal surgery or radiation.

A retrospective study of open and endoscopic nephron sparing surgery in the treatment of complex renal tumors

Objective:

To investigate clinical outcomes of open and retroperitoneal laparoscopic nephron-sparing surgery in the treatment of complex renal tumours.

Methods:

A retrospective case study was conducted. Patients with complex renal tumours admitted to our hospital between January 2018 and September 2019 were enrolled; the included patients (n=40) were divided into the observation group (open partial nephrectomy, n=20) and control group (laparoscopic partial nephrectomy, n=20) according to operation modes. The operation time, renal warm ischaemia time, intraoperative blood loss, renal pedicle blocking time, intestinal function recovery time, postoperative hospital stay, and postoperative complications were recorded.

Results:

Significant differences were noted regarding renal warm ischaemia time, renal pedicle blocking time, intraoperative blood loss, operation time, and postoperative hospital stay between the observation and control groups (P<0.05); however, no significant difference was observed in intestinal function recovery time and postoperative drainage days (P>0.05).

Conclusion:

Open surgery remains the recommended surgical method for the treatment of few complex tumours in the renal hilus region and has gradually become the renal surgery of choice at present, although laparoscopic surgery has evolved tremendously.
