We compared pathological evaluation and postoperative recovery in patients undergoing transperitoneal laparoscopic nephrectomy at our institution with morcellated vs intact specimen extraction.
A prospective evaluation of 57 consecutive patients undergoing radical and simple transperitoneal laparoscopic nephrectomy was reviewed. One patient was excluded from study due to transitional cell carcinoma, which was detected intraoperatively. The 33 morcellated specimens were extracted at the umbilical port and the 23 intact specimens were extracted through a midline infraumbilical incision. Data were obtained on narcotic requirements, hospital stay, complications, estimated blood loss, mass size based on preoperative imaging, specimen weight and extraction incision length.
Mean incision length in the morcellated and intact specimen removal groups was 1.2 and 7.1 cm, respectively (p <0.001). No significant differences in pain or recovery were noted between the 2 groups. Two cases of microscopic invasion of the perinephric adipose tissue in the intact specimen group were up staged from clinical T1 to pT3a disease. No change in patient treatment was made based on this information.
We did not find a significant difference in surgical time, pain or hospital stay. Only incision length was statistically significant. Postoperative recovery appeared to be similar in these 2 groups. With modern imaging modalities information on pathological stage did not alter patient treatment.

    • "Since introduction of laparoscopic radical nephrectomy (LRN) the procedure has been refined and adopted as a standard of care for appropriate renal masses, with advantages including decreased blood loss, lower narcotic requirements, shorter hospital stays, and more rapid return to normal activities while maintaining equivalent short-and long-term oncologic efficacy compared with open radical nephrectomy [3] [4] [5]. These improved outcomes are thought in large part to be a result of the smaller incisions, and thus laparoscopy has rapidly emerged as standard of care for radical nephrectomy [6]. Similar to the introduction of LRN with its equivalent oncologic outcomes and improved morbidity profile, with the advent of improved laparoscopic surgical instrumentation and refinements in technique, LPN has emerged as a viable alternative to open partial nephrectomy (OPN) with equivalent short-and intermediate-term outcomes for selected patients [7] [8].

    ABSTRACT: Introduction. Laparo-endoscopic single-site surgery (LESS) may diminish morbidity of laparoscopic surgery. We prospectively evaluated feasibility and outcomes of LESS-Radical Nephrectomy (LESS-RN) and Partial Nephrectomy (LESS-PN). Methods. 10 patients underwent LESS-RN (6) and LESS-PN (4) between 2/2009-5/2009. LESS-RN included 2 with renal vein thrombectomy, one of which was also cytoreductive. Transperitoneal LESS access was obtained by periumbilical incision. Patient/tumor characteristics, oncologic, and quality of life (QoL) outcomes were analyzed. Results. 3 Men/7 Women (mean age 58.7 years, median follow-up 9.8 months) underwent LESS. 9/10 cases were completed successfully. All had negative margins. Mean operative time was 161 minutes, estimated blood loss was 125 mL, and incision size was 4.4 cm. Median tumor size for LESS-RN and -PN was 5.0 and 1.7 cm (P = .045). Median LESS-PN ischemia time was 24 minutes; mean preoperative/postoperative creatinine were 0.7/0.8 mg/dL (P = .19). Mean pain score at discharge was 1.3. Mean preoperative, 3-, and 6-month postoperative SF-36 QoL Score was 73.8, 74.4 and 77.1 (P = .222). All patients are currently alive. Conclusions. LESS-RN, renal vein thrombectomy, and PN are technically feasible and safe while maintaining adherence to oncologic principles, with excellent QoL preservation and low discharge pain scores. Further study is requisite.

    ABSTRACT: To estimate the efficacy of the laparoscopic radical nephrectomy we analyzed the clinical data of our series. One hundred eighty five patients were enrolled in our laparoscopic radical nephrectomy program between July, 1992 and July, 2001. Of the 185 patients, 146 had small renal tumors (smaller than 5 cm in diameter) and 39 had large tumors (equal to or more than, 5 cm in diameter). Under a laparoscope the kidney, adrenal gland, and perirenal fatty tissue were dissected in an en bloc fashion. In case of taking out a small tumor, the specimen was fractionated within the sack to avoid an additional skin incision after entrapping in the laparoscopy sack in the working space. In case of a large tumor, regional lymph nodes dissection was done and the specimen was taken out intact in the sack through an enlarged incision. Our laparoscopic procedure was successful in 171 of the 185 cases; 14 patients required open surgery because of bleeding from an injured vessels or treatment for other injured organs. The mean operative time was 4.7 hours for both small and large tumors. Estimated blood loss was between 237 and 380 ml on average for small and large tumors, respectively. Full convalescence was achieved around 3 weeks after operation in both groups. Only one patient who had large tumor was found to have micrometastasis in 1 of 5 regional lymph nodes. Recurrences were observed in 4 cases of the small tumor group and in 2 cases of the large tumor group during 1 to 108 months of follow-up. Laparoscopic radical nephrectomy is a very useful and safe surgical procedure for renal cell carcinoma.
