Integration of laparoscopic partial nephrectomy into an Australian public hospital: three-year follow-up of our initial 50 cases

National nephrectomy registries: Reviewing the need for population-based data

Nephrectomy is the cornerstone therapy for renal cell carcinoma (RCC) and continued refinement of the procedure through research may enhance patient outcomes. A national nephrectomy registry may provide the key information needed to assess the procedure at a national level. The aim of this study was to review nephrectomy data available at a population-based level in Australia and to benchmark these data against data from the rest of the world as an examination of the national nephrectomy registry model. A PubMed search identified records pertaining to RCC nephrectomy in Australia. A similar search identified records relating to established nephrectomy registries internationally and other surgical registries of clinical importance. These records were reviewed to address the stated aims of this article. Population-based data within Australia for nephrectomy were lacking. Key issues identified were the difficulty in benchmarking outcomes and no ongoing monitoring of trends. The care centralization debate, which questions whether small-volume centers provide comparable outcomes to high-volume centers, is ongoing. Patterns of adherence and the effectiveness of existing protocols are uncertain. A review of established international registries demonstrated that the registry model can effectively address issues comparable to those identified in the Australian literature. A national nephrectomy registry could address deficiencies identified in a given nation's nephrectomy field. The model is supported by evidence from international examples and will provide the population-based data needed for studies. Scope exists for possible integration with other registries to develop a more encompassing urological or surgical registry. Need remains for further exploration of the feasibility and practicalities of initiating such a registry including a minimum data set, outcome indicators, and auditing of data.

Outcomes of open partial nephrectomies performed by Australian trainees

BACKGROUND

Partial nephrectomy (PN) has become the standard of care for small renal tumours, with open partial nephrectomy (OPN) being superseded by minimally invasive PN. Advances in minimal access surgery have resulted in fewer relative contraindications, with subsequently fewer OPN being performed. Consequentially, trainees have less opportunity to gain skills and experience in open renal surgery. The aims of this study were to assess the standard of OPN performed by Australian urological trainees and to define whether OPN is a safe and suitable training opportunity.

METHOD

A retrospective review was undertaken on patients who underwent OPN performed by urology trainees from 2010 to 2014 at two training hospitals in Western Australia. Data collected included patient demographics, surgical and oncological outcomes and morbidity.

RESULTS

Sixty patients underwent OPN, with a mean age of 56 years. Most tumours were single, with mean size 31 mm. Mean operative time was 157 min, with a mean cold ischaemic time of 27 min. Mean pre- and post-operative creatinine levels were equivalent (77 μmol/L). The overall complication rate was 18%, with no documented urinary leaks, and 1.7% blood transfusion rate. Median length of stay was 4 days. There were no oncological positive margins or recurrence after a median follow-up of 2 years.

CONCLUSION

Our data support the notion that Australian urological trainees can perform the majority of OPN cases, with equivalent oncological outcomes. We would advocate that when an OPN is being performed, the supervising consultant should use the case as an adjuvant for open renal surgery training.
