Pre Treatment

Background Radiofrequency ablation (RFA) and laparoscopic partial nephrectomy (LPN) are used to treat small renal masses (SRM; ≤4 cm), although there are conflicting results in the changes in creatinine and estimated glomerular filtration rate (eGFR) after treatment. On contrast-enhanced computed tomography (CE-CT) images, the quantity and quality of renal function can be evaluated by calculating the split renal function (SRF). Purpose To compare renal function after RFA or LPN treatment of SRMs through evaluation of the SRF in the affected kidney. Material and Methods Single T1a renal tumors successfully treated with RFA (n = 60) or LPN (n = 31) were retrospectively compared. The SRF was calculated on pre-treatment CE-CT images and the first follow-up exam after completed treatment. Serum creatinine and eGFR values were collected simultaneously. To compare renal function outcomes, Student’s t-test and multivariable linear regression models (adjusted to RFA/LPN treatment, pre-treatment SRF/eGFR, BMI, age, tumor characteristics, and Charlson Comorbidity Index) were used. Results SRF was reduced in both groups, although reduction was greater in the LPN group (LPN –5.7%) than in the RFA group (RFA –3.5%; P = 0.013). After adjusted analysis, the LPN group still had greater SRF reduction (difference 3.2%, 95% confidence interval 1.3–1.5; P = 0.001). There was no difference between groups in the change of creatinine/eGFR after treatment. Conclusion Both RFA and LPN are nephron-sparing when treating SRMs. However, in this series, reduction of SRF in the affected kidney was smaller after RFA, having a more favorable preservation of renal function than LPN.

Objectives: To evaluate oncological feasibility and oncological and functional results of retroperitoneal sutureless zero ischemia laparoscopic partial nephrectomy (LPN). Patients and methods: Patients with posterior renal masses with low nephrometry score (RENAL ≤ 7) treated who underwent retroperitoneal sutureless zero ischemia.in a single center from January 2016 to November 2017. Clinical, surgical and pathological data were prospectively collected. Complications were reported according to the modified Clavien classification. Results: Retroperitoneal sutureless zero ischemia laparoscopic partial nephrectomy was performed on 15 patients. The indication for nephron-sparing surgery was elective in 11 (73%) patients and imperative in 4 (27%). Median RENAL score was 5 (IQR: 5-7), median tumor diameter 25 mm (IQR: 20-35). In 11 cases, the tumor was located polar (85%), and in 2 cases hilar (15%). There were no intraoperative complications. No cases were converted to radical nephrectomy, and in no case parenchyma suture was necessary. Median operative time was 90 min (IQR:40-150), in no case clamping of the renal artery was necessary, median hospital stay was 4 days, median estimated blood loss (EBL) was 310 (180-500) ml. Pathological analysis showed renal cell carcinoma in 11 patients (85%), 9 (60%) staged T1a and 2 (13%) T1b. In 4 (27%) an oncocytoma was found. There were no positive surgical margins. One patient developed a major postoperative complication (postoperative renal bleeding requiring super-selective embolization). Trifecta rate was 93%. Conclusions: Sutureless retroperitoneal zero ischemia LPN for the treatment of low-complexity posterior renal masses showed to be safe and feasible. Longer follow-up and higher numbers of patients are, however, warranted to draw definitive conclusions on functional outcomes.
