Retroperitoneal single-port laparoscopic urologic surgery, particularly in patients requiring free-hand suturing, is technically feasible. The initial clinical experience of organ-ablative, extirpative, and reconstructive surgery with this approach is reported.

Urologists should suspect intravesical mesh erosion or stone formation in patients with persistent pain, hematuria, or bladder irritation symptoms after MUS procedures. The TUR was a useful treatment modality for patients with intravesical complications after MUS procedures.

PurposeWe analyzed a series of patients who had undergone laparoscopic partial nephrectomies (LPNs) and open partial nephrectomies (OPNs) to compare outcomes of the two procedures in patients with pathologic T1a renal cell carcinomas (RCCs).Materials and MethodsFrom January 1998 to May 2009, 417 LPNs and 345 OPNs were performed on patients with small renal tumors in 15 institutions in Korea. Of the patients, 273 and 279 patients, respectively, were confirmed to have pT1a RCC. The cohorts were compared with respect to demographics, peri-operative data, and oncologic and functional outcomes.ResultsThe demographic data were similar between the groups. Although the tumor location was more exophytic (51% vs. 44%, p=0.047) and smaller (2.1 cm vs. 2.3 cm, p=0.026) in the LPN cohort, the OPN cohort demonstrated shorter ischemia times (23.4 min vs. 33.3 min, p<0.001). The LPN cohort was associated with less blood loss than the OPN cohort (293 ml vs. 418 ml, p<0.001). Of note, two patients who underwent LPNs had open conversions and nephrectomies were performed because of intra-operative hemorrhage. The decline in the glomerular filtration rate at the last available follow-up (LPN, 10.9%; and OPN, 10.6%) was similar in both groups (p=0.8). Kaplan-Meier estimates of 5-year local recurrence-free survival (RFS) were 96% after LPN and 94% after OPN (p=0.8).ConclusionsThe LPN group demonstrated similar rates of recurrence-free survival, complications, and postoperative GFR change compared with OPN group. The LPN may be an acceptable surgical option in patients with small RCC in Korea.
