Health-related quality of life after retroperitoneoscopic and hand-assisted laparoscopic nephrectomy.

BACKGROUND AND PURPOSE: The assessment of postoperative recovery typically involves the use of measures that are open to bias. Whilst there has been some work done on the short-term postoperative recovery comparison for hand-assisted laparoscopic nephrectomy (HALN) and retroperitoneoscopic nephrectomy (RPN), to our knowledge, this is the first study to look at long-term health outcomes for these two procedures. This study sought objectively to compare long-term postoperative health-related quality of life (HRQoL) after retroperitoneoscopic and hand-assisted transperitoneal laparoscopic nephrectomy undertaken for renal pathology. This was achieved by both reviewing perioperative data from medical records and by using the SF-36 questionnaire postoperatively. PATIENTS AND METHODS: Patients who had undergone elective retroperitoneoscopic (N = 19) or transperitoneal HALN (N = 32) between 2001 and 2004 at our institution underwent objective HRQoL assessment via a validated telephone questionnaire (SF-36) and by review of postoperative data from the medical records. This survey was administered between 3 and 6 months after surgery. The data then underwent statistical analysis using the paired Student's t-test. RESULTS: Perioperative data showed no significant difference in the postoperative complication rate in the two groups. The HRQoL scores gathered from the SF-36 questionnaire gave mean scores of 67.4 and 68.5 for the HALN and RPN groups, respectively (100 represents maximum quality of life). This difference was not statistically significant. CONCLUSIONS: This is the first study to look at long-term (mean follow-up 6 months) health outcomes for patients undergoing RPN and HALN. The results show no greater long-term health benefit for one procedure over the other. This finding supports the data in the literature on the benefits of HALN over RPN in terms of a less protracted learning curve, greater technical ease, fewer intraoperative complications, and consequently reduced operating times with no loss of the long-term health benefit that is traditionally associated with the standard laparoscopic technique.

Which is the real gold standard for small-volume renal tumors? Radical nephrectomy versus nephron-sparing surgery.

BACKGROUND AND PURPOSE: Until recently, the gold standard for treatment of localized renal-cell carcinoma with a normal contralateral unit was deemed to be a formal radical nephrectomy. Advocates of nephron-sparing surgery have recently challenged this concept; we wished to evaluate the evidence to determine which treatment is objectively superior for patients with renal tumors up to 4 cm. MATERIALS AND METHODS: MEDLINE, CANCERLIT, and EMBASE computer literature searches were performed to identify peer-reviewed papers pertaining to radical nephrectomy (RN), nephron-sparing surgery (NSS), or comparisons of these methods for tumors as large as 4 cm in maximum diameter. Review of the bibliographies of recovered articles and data in recent textbooks were used to supplement the computerized searches. There were a total of 797 cases in the RN group and 1211 in the NSS group. The parameters specifically evaluated were evidence of local recurrence, disease progression, and death within 33 months, this period being chosen primarily because it was the shortest follow-up in the studies evaluated. The data were then subjected to rigorous statistical analysis. Laparoscopic radical nephrectomy (LRN) and laparoscopic nephron-sparing surgery (LNSS) articles were also reviewed; however, current follow-up periods were considered too short to draw a statistically significant conclusion. RESULTS: Disease-specific survival rates (P=0.001; Mann-Whitney test) as well as the incidence of metastases (P<0.05; Mann-Whitney test) were significantly better in the NSS group. The incidence of local recurrence (P=0.22; Mann-Whitney test) was not significantly different. It should be borne in mind that there are different follow-up periods for each study, and this may have had an impact on the results. CONCLUSION: Nephron-sparing surgery seems to be as effective as RN in patients with renal cell tumours up to 4 cm, although only a large randomized controlled trial with long follow-up periods would provide a definite answer.

The issue of prophylactic antibiotics prior to flexible cystoscopy.

OBJECTIVE: The aim of this study was to determine whether single-dose parenteral antibacterial therapy significantly alters the rate of infection in patients undergoing flexible cystourethroscopy. PATIENTS AND METHODS: 162 patients were studied prospectively having either received parenteral antibacterial chemoprophylaxis prior to flexible cystourethroscopy or not. Pre- and postprocedure mid stream samples of urine (MSSU) were obtained to objectively evaluate the presence of infection. RESULTS: Gentamicin prophylaxis reduced the rate of post-cystoscopy-positive MSSUs from 21 to 5%. CONCLUSION: The surprisingly high rate of infection after flexible cystoscopy was significantly reduced by a single dose of gentamicin.
