Predictive factors of prolonged warm ischemic time (?30 minutes) during partial nephrectomy under pneumoperitoneum.

ABSTRACT:

Purpose

Current clinical data support a safe warm ischemia time (WIT) limit of 30 minutes during laparoscopic partial nephrectomy (LPN) or robot-assisted partial nephrectomy (RPN). We evaluated independent factors predicting prolonged WIT (more than 30 minutes) after LPN or RPN.

Materials and methods

A retrospective data review was performed for 317 consecutive patients who underwent LPN or RPN performed by the same surgeon from October 2007 to May 2013. Patients were divided into two groups: group A was defined as prolonged WIT (?30 minutes) and group B as short WIT (<30 minutes). We compared clinical factors between the two groups to evaluate predictors of prolonged WIT.

Results

Among 317 consecutive patients, 80 were in the prolonged WIT group. Baseline characteristics were not significantly different between the groups. In the univariable analysis, PADUA (preoperative aspects and dimensions used for an anatomical) score (p=0.001), approach method (transperitoneal or retroperitoneal approach; p<0.001), and surgeon experience (p<0.001) were significantly associated with prolonged WIT. In the multivariable analysis, PADUA score (p=0.032), tumor size (?25 mm; odds ratio, 2.98; 95% confidence interval, 1.48-5.96; p=0.002), and surgeon experience (p<0.001) were independent predictors of prolonged WIT.

Conclusions

Surgeon experience, tumor size, and PADUA score predicted prolonged WIT after RPN or LPN. Among these factors, increasing surgical experience with LPN or RPN is the most important factor for preventing prolonged WIT.

Project description:BackgroundPartial nephrectomy and radical nephrectomy are the relevant surgical therapy options for localised renal cell carcinoma. However, debate regarding the effects of these surgical approaches continues and it is important to identify and summarise high-quality studies to make surgical treatment recommendations.ObjectivesTo assess the effects of partial nephrectomy compared with radical nephrectomy for clinically localised renal cell carcinoma.Search methodsWe searched CENTRAL, MEDLINE, PubMed, Embase, Web of Science, BIOSIS, LILACS, Scopus, two trial registries and abstracts from three major conferences to 24 February 2017, together with reference lists; and contacted selected experts in the field.Selection criteriaWe included a randomised controlled trial comparing partial and radical nephrectomy for participants with small renal masses.Data collection and analysisOne review author screened all of the titles and abstracts; only citations that were clearly irrelevant were excluded at this stage. Next, two review authors independently assessed full-text reports, identified relevant studies, evaluated the eligibility of the studies for inclusion, assessed trial quality and extracted data. The update of the literature search was performed by two independent review authors. We used Review Manager 5 for data synthesis and data analyses.Main resultsWe identified one randomised controlled trial including 541 participants that compared partial nephrectomy to radical nephrectomy. The median follow-up was 9.3 years.Based on low quality evidence, we found that time-to-death of any cause was decreased using partial nephrectomy (HR 1.50, 95% CI 1.03 to 2.18). This corresponds to 79 more deaths (5 more to 173 more) per 1000. Also based on low quality evidence, we found no difference in serious adverse events (RR 2.04, 95% CI 0.19 to 22.34). Findings are consistent with 4 more surgery-related deaths (3 fewer to 78 more) per 1000.Based on low quality evidence, we found no difference in time-to-recurrence (HR 1.37, 95% CI 0.58 to 3.24). This corresponds to 12 more recurrences (14 fewer to 70 more) per 1000. Due to the nature of reporting, we were unable to analyse overall rates for immediate and long-term adverse events. We found no evidence on haemodialysis or quality of life.Reasons for downgrading related to study limitations (lack of blinding, cross-over), imprecision and indirectness (a substantial proportion of patients were ultimately found not to have a malignant tumour). Based on the finding of a single trial, we were unable to conduct any subgroup or sensitivity analyses.Authors' conclusionsPartial nephrectomy may be associated with a decreased time-to-death of any cause. With regards to surgery-related mortality, cancer-specific survival and time-to-recurrence, partial nephrectomy appears to result in little to no difference.
