Nephrectomy for benign disease in the UK: results from the British Association of Urological Surgeons nephrectomy database.

OBJECTIVE: To summarize the practice of UK urologists with regard to nephrectomy for benign disease, documenting the indications, procedural techniques and outcomes. METHODS: All patients undergoing nephrectomy for a benign condition in 2012 were identified from the British Association of Urological Surgeons (BAUS) nephrectomy database. Recorded variables included the technique of surgery, the type of minimally invasive procedure, operating time, blood loss, transfusion rate, conversion rate, intra- and postoperative complications and mortality rate. Cases were also sub-analysed according to their pathologies to determine the differences in complication rate between stone disease, pyelonephritis, non-functioning kidney and other benign lesions. To contextualize procedural complexity, the simple nephrectomy data were compared with those obtained from the BAUS stage T1 radical nephrectomy audit. RESULTS: A total of 1 093 nephrectomies were performed (537 non-functioning kidneys, 142 stone disease, 129 nephrectomies secondary to pyelonephritis and 285 cases with other benign conditions). Of these, 76% were performed laparoscopically. Blood loss >500 mL was noted in 74 cases with a 4.8% blood transfusion rate. The intra- and postoperative complication rates were 5.2 and 11.9%, respectively. Of the 847 minimally invasive procedures, the conversion rate was 5.9%. Patients with stone disease have the highest intra- and postoperative complications (9.9 and 23.9%, respectively) compared with other benign pathologies. The total number of T1 radical nephrectomies performed was 1 095. In comparison with T1 radical nephrectomy, simple nephrectomy carries an increased risk of conversion to an open procedure (1.8 times), a higher rate of blood transfusion (4.8 vs 2.8%), and a higher risk of intra- and postoperative complications (5.2 vs 3.7% and 11.9 vs 10%, respectively). CONCLUSION: The present study reports the largest series of nephrectomies performed for benign disease and the resultant data now support the bespoke preoperative counselling of patients. Furthermore, it confirms the commonly held view that simple nephrectomy can be more difficult than its radical counterpart. The authors suggest that the term 'simple nephrectomy' is changed to 'benign nephrectomy'.

The use of prostate-specific antigen testing in men presenting with haematuria.

OBJECTIVES: To analyse prostate-specific antigen (PSA) levels and clinical outcome in men presenting with haematuria, to develop an evidence-base for the use of PSA testing in this setting, as haematuria is a known complication of locally invasive prostate cancer, and so PSA levels are often measured in patients presenting with haematuria. PATIENTS AND METHODS: We reviewed the records of 637 men presenting with haematuria to our urology department between April 2002 and June 2005. RESULTS: Of 373 men aged 50-79 years, 278 (75%) had their PSA level measured, and 50 were abnormal. Prostate biopsies were taken in 27 men with an abnormal PSA level (54%) and one man with a normal PSA level but an abnormal digital rectal examination. Prostate cancer was detected in 22 patients (8% of those tested, and 71% of those biopsied); 4.7% of all men presenting with macroscopic haematuria and aged 50-79 years were found to have prostate cancer, vs 8.5% of those with microscopic haematuria. CONCLUSIONS: We report a higher proportion of prostate cancers in men presenting with haematuria and aged 50-79 years than reported in previous screening studies, and a cancer detection rate of 71% of those biopsied, which is at least double the detection rates seen in screening studies. In the absence of a prospective controlled trial, PSA testing will remain part of our protocol for both macroscopic and microscopic haematuria.
