Objective To determine if massive renal size should be a contraindication for attempting a laparoscopic approach to bilateral native nephrectomies in patients with autosomal dominant polycystic kidney disease ( ADPKD ). Patients and Methods We retrospectively reviewed all laparoscopic bilateral nephrectomies performed for ADPKD at our institution from 1 J anuary 2000 to 31 D ecember 2012. We stratified patients by kidney weight (with or without at least one kidney weighing >2500 g) and compared perioperative data, complications, and status of kidney allografts. Additionally, the subset of patients with at least one kidney weighing >3500 g was compared with the rest of the cohort. Results We identified 68 patients; mean (range) individual kidney weight was 1984 (197–5042) g. In all, 24 patients had at least one kidney weighing >2500 g, yet patients in this group were not significantly different from the rest of the cohort for complications, estimated blood loss, transfusion rate, or duration of hospitalisation. For those who underwent simultaneous renal allotransplantation, native kidney size was not associated with graft outcomes. Additionally, of the six patients with at least one kidney weighing >3500 g, only one required a blood transfusion, and the group had no intraoperative or postoperative Clavien grade ≥3 complications. None of the cohort required conversion to open surgery. Conclusion Massive size of polycystic kidneys is not a contraindication to attempting a laparoscopic approach to bilateral nephrectomies in an experienced, high‐volume centre.

ObjectiveTo examine the impact of body mass index, as a measure of obesity, on the surgical outcomes of cystectomy.MethodsThe American College of Surgeons National Surgical Quality Improvement Program database was used to acquire data on 1293 cystectomies carried out from 2005 to 2011. Patients were divided into two groups: body mass index <30 kg/m2 and ≥30 kg/m2. A propensity score‐matched analysis of perioperative outcomes was carried out.ResultsA total of 869 patients had a body mass index <30, whereas 424 had a body mass index ≥30. Unadjusted comparisons showed higher rates of superficial surgical site infections (8.7% vs 5.3%, P = 0.04), renal insufficiency (4.0% vs 1.7%, P = 0.01) and increased operative times (365.7 min vs 338.6 min, P = 0.0004) in the obese patients, but interestingly lower rates of pneumonia (2.4% vs 4.8, P = 0.03) and cerebral vascular accidents (0.0% vs 0.9%, P = 0.05). However, the latter two observations might be explained by more tobacco use among non‐obese patients (26.6 mean pack‐years vs 20.0 mean pack‐years, P = 0.004). Notably, no differences in 30‐day mortality were noted. After adjusting for preoperative demographic and clinical data using propensity score‐matching methods, there were no observed differences between the two cohorts except for operative time (P = 0.04).ConclusionsObesity is not independently associated with an increased risk of perioperative complications or 30‐day mortality after cystectomy.

Objective To present the first age‐stratified assessment of outcomes after holmium laser enucleation of the prostate ( HoLEP ) for the treatment of lower urinary tract symptoms resulting from prostate enlargement. Patients and Methods We retrospectively analysed and compared the morbidity, and the peri‐operative and functional outcomes of patients aged 50–59, 60–69, 70–79 and ≥80 years. Complications at 30 days were stratified using the C lavien system. Functional outcomes were assessed using the I nternational P rostate S ymptom S core ( IPSS ), maximum urinary flow rate ( Q max ), post‐void residual urine volume ( PVR ) and urinary continence. Results A total of 311 patients underwent HoLEP for obstructive voiding symptoms from A ugust 2007 to J une 2011, of whom 22 patients were aged 50–59 years, 91 were aged 60–69 years, 153 were aged 70–79 years, and 45 were aged ≥80 years. The overall morbidity rates were similar among the age groups (20, 24.4, 21.6 and 22.1% for groups 1, 2, 3 and 4, respectively), as were the incidence of significant complications ( C lavien grade ≥ III ), change in serum haemoglobin level, and length of hospital stay. Patients ≥80 years did have a longer catheterization time (3.4 days) than patients aged 50–59 years (1.68 days). By 1 year there were no significant differences in urinary continence, IPSS , Q max , or PVR among the age groups. Conclusions Overall morbidity, hospital stay, and 1‐year functional outcomes of HoLEP were similar among all age groups. This study shows that HoLEP is a safe and effective treatment for benign prostatic hyperplasia regardless of age.
