Introduction:
Radical prostatectomy (RP) is a common surgical procedure with a risk of postoperative erectile dysfunction and urinary incontinence. There is a need for data on RP as a basis for quality assurance and benchmarking.
Methods:
In 2015, prostatectomies in Sweden (PiS) form was implemented in the National Prostate Cancer Register (NPCR) of Sweden with data on pre-, peri- and post-operative variables.
Results:
Out of all radical prostatectomies performed in 2016 in Sweden, 3096/3881 (80%) were registered in PiS. A total of 2605 (84%) were robot-assisted radical prostatectomy (RARP) and 491 (16%) were RRP (retropubic radical prostatectomy). RARP was performed by 91 surgeons of whom 47% operated more than 25 RP/year; and RRP was performed by 69 surgeons of whom 10% performed more than 25 RP/year. RARP had a longer operative time (median operating time: RARP 155 minutes [IQR 124-190]; RRP 129 minutes [IQR 105-171]; P < .001) but was associated with smaller bleeding (median intraoperative blood loss: RARP 100 mL [IQR 50-200], RRP 700 mL [IQR 500-1100]; P < .001).
Conclusions:
We report on a nationwide, population-based register with transparent reporting of data on the performance of radical prostatectomy. These data are needed as a basis for quality assurance with comparisons of results from individual surgeons and hospitals.

Testing a Claim about Mean: Known Population SD
Estimating a population mean requires the samples to be distributed normally. The data should be collected from the randomly selected samples having no sampling bias. The sample size needed to be higher than 30, and most importantly, the population standard deviation should be already known.
In most realistic situations, the population standard deviation is often unknown, but in rare circumstances, when it...
