Review Meta Analysis
Laparoendoscopic single-site (LESS) vs laparoscopic living-donor nephrectomy: a systematic review and meta-analysis.
The aim of this study was to provide a systematic review and meta-analysis of reports comparing laparoendoscopic single-site (LESS) living-donor nephrectomy (LDN) vs standard laparoscopic LDN (LLDN). A systematic review of the literature was performed in September 2013 using PubMed, Scopus, Ovid and The Cochrane library databases. Article selection proceeded according to the search strategy based on Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria. ⋯ This procedure offers comparable surgical and early functional outcomes to the conventional LLDN, with a lower analgesic requirement. However, it is more technically challenging than LLDN, as shown by a greater likelihood of conversion. The role of LESS LDN remains to be defined.

To compare the effectiveness of robot-assisted and standard laparoscopic prostatectomy. ⋯ Men undergoing robotic prostatectomy appear to have reduced surgical morbidity, and a lower risk of a positive surgical margin, which may reduce rates of cancer recurrence and the need for further treatment, but considerable uncertainty surrounds these results. We found no evidence that men undergoing robotic prostatectomy are disadvantaged in terms of early outcomes. We were unable to determine longer-term relative effectiveness.

Review Meta Analysis
Intravesical chemotherapy plus bacille Calmette-Guérin in non-muscle invasive bladder cancer: a systematic review with meta-analysis.
WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Non-muscle-invasive bladder cancer has a significant recurrence and progression rate despite transurethral resection. The current standard of care to lower the risk of recurrence and progression is adjuvant BCG followed by maintenance BCG. Despite this, a significant number of patients experience recurrence and progress to invasive cancer. Several randomized trials have studied combination therapy (BCG with chemotherapy) to try to reduce the recurrence and progression rate. We performed a systematic review with meta-analysis and found that adjuvant BCG followed by maintenance therapy is the appropriate standard of care when compared with combination therapy. We conclude that further trials are warranted to test the effects of adding chemotherapy to BCG in patients with Ta or T1 disease, but not in those with Tis alone. ⋯ Adjuvant therapy with induction BCG followed by maintenance BCG is the appropriate standard of care for patients with resected NMIBC at high risk of recurrence. Further trials are warranted to test the effects of adding chemotherapy to BCG in patients with Ta or T1 disease, but not in those with Tis alone.

Review Meta Analysis Comparative Study
Comparison of transperitoneal and retroperitoneal laparoscopic nephrectomy for renal cell carcinoma: a systematic review and meta-analysis.
WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Laparoscopic nephrectomy is now considered to be the reference procedure for kidney cancer. It can be performed via a transperitoneal or retroperitoneal approach. Each approach has its advantages and disadvantages. No definitive conclusions regarding objective difference between the two approaches have been reached to date. This meta-analysis indicates that in appropriately selected patients, especially patients with posteriorly located renal tumors, the retroperitoneal approach may be faster and equally safe compared with the transperitoneal approach. ⋯ This meta-analysis indicates that, in appropriately selected patients, especially patients with posteriorly located renal tumours, the retroperitoneal approach may be faster and equally safe compared with the transperitoneal approach. Despite our rigorous methodology, conclusions drawn from our pooled results should be interpreted with caution because of the inherent limitations of the included studies.

Review Meta Analysis
Examining the 'gold standard': a comparative critical analysis of three consecutive decades of monopolar transurethral resection of the prostate (TURP) outcomes.
What's known on the subject? and What does the study add? Transurethral resection of the prostate (TURP) remains the dominant and definitive treatment for lower urinary tract symptoms due to benign prostatic hyperplasia (LUTS-BPH), but the widespread use of medical therapies (particularly monotherapies) for rapid symptom improvement has meant that the most common indication for TURP has shifted to moderate-severe medical therapy refractory LUTS to, coupled with abnormal objective parameters, or when complications arise. Patients undergoing TURP as part of contemporary randomised controlled trials are not older but have a larger preoperative prostate volume and reduced major morbidity compared with large cohort studies from successive past eras. Delayed surgery because of prolonged medical monotherapy may explain a higher reported failure to void rate, possibly because of negative impact on detrusor function from unrelieved obstruction. ⋯ The higher reported failure to void rate, may possibly reflect worse detrusor function at time of TURP. Delaying surgery by prolonged medical monotherapy may compound this. Trials methodology in this area requires quality improvement and standardisation in future.
