Summary
Sutureless partial nephrectomy (SLPN) is effective, with only 5.9% of cases converting to standard partial nephrectomy (SPN). Key predictors for conversion include patient age, kidney function (eGFR), and tumor characteristics.
Area of Science:
- Urology
- Surgical Oncology
- Nephrology
Background:
- Sutureless partial nephrectomy (SLPN) offers a minimally invasive approach for localized renal tumors.
- Assessing conversion rates from SLPN to standard partial nephrectomy (SPN) is crucial for surgical planning.
Purpose of the Study:
- To determine the conversion rate of SLPN to SPN.
- To identify preoperative factors predicting the need for conversion during SLPN.
Main Methods:
- Retrospective analysis of 353 adult patients undergoing SLPN between 2016-2023.
- Logistic regression used to identify preoperative predictors for conversion to SPN.
Main Results:
- 21 of 353 SLPN cases (5.9%) were converted to SPN.
- Conversion rates differed between laparoscopic (7.9%) and robotic (2.9%) approaches (P=.066).
- Significant predictors for conversion included younger age, higher preoperative eGFR, larger tumor size, and exophytic/endophytic tumor characteristics.
Conclusions:
- SLPN is an effective and feasible technique for renal tumors.
- Preoperative factors like patient age, eGFR, and tumor characteristics predict the likelihood of conversion to SPN, aiding surgical strategy refinement.
