Objective: To investigate the cause‐specific mortality in the postoperative period after radical prostatectomy (RP) for prostate cancer (PCa). Methods: In the National Prostate Cancer Register of Sweden (NPCR), we identified all men who died within 90 days after RP performed 1998–2018 and we assessed cause of death in a chart review. We compared the adjudications of death from our medical record review with those in in the Swedish Cause of Death Registry (CDR). Results: Out of 44 635, 58 (0.13%) men who had undergone RP from 1998 through 2018 died within 90 days after RP. Per medical record review the most common causes of death were cardiac disease (30%) and venous thromboembolic events (VTE; 21%). No men died of metastatic PCa as was first indicated in the CDR. After robot‐assisted RP (RARP) or open retropubic RP (RRP), the postoperative mortality was 0.09% (19/21 520) and 0.19% (37/19 635), respectively. The effect off modality was confounded mainly by year of surgery, age at surgery, Charlson Comorbidity Index score and the concomitant pelvic lymph node dissection. Conclusion: The validated absolute 90‐day mortality after RP was 1.3/1000 during the 21‐year study period. Cardiovascular diseases were the most common causes of death after RP. Our validation of the CDR refuted the occurrence of postoperative deaths from metastatic PCa. There were differences in rates and type of mortality between RRP and RARP, but the RARP cohort was more recent than the RRP cohort, which likely explain the differences. [ABSTRACT FROM AUTHOR]

Objective To evaluate the risk of different in-hospital complications for patients undergoing a radical cystectomy ( RC), as limited nationwide population data on short- and long-term complications after RC is available, despite it being the standard treatment for localised muscle-invasive urinary bladder cancer ( UBC)., Patients and Methods In all, 7608 persons underwent a RC after UBC diagnosis, as registered in the Swedish National Patient Register between 1964 and 2008., We estimated the frequency and incidences and calculated hazard ratios ( HR) and 95% confidence intervals ( CI) using multivariate Cox proportional hazards models., Results Urinary tract infection/septicaemia was the most common complication following radical cystectomy, with an incidence of 90.4 per 1,000 person years., There was a higher risk of urinary tract infection among patients who had a continent cutaneous reservoir ( HR: 1.11 (0.94-1.30) or orthotopic neobladder 1.21 (1.05-1.39) than among those with ileal conduit., Similarly, continent cutaneous reservoir and orthotopic neobladder were associated with increased risks for wound and abdominal wall hernias, stones in the urinary tract, hydronephrosis and nephrostomy tube treatment, and kidney failure., In contrast, risk of bowel obstruction was lower among those with orthotopic neobladder than those with ileal conduit ( HR: 0.64 (0.50-0.81)) and those with continent cutaneous reservoir ( HR: 0.92 (0.73-1.16)., Conclusions In-hospital complications after RC are numerous and continue to accumulate for many years after surgery, indicating the need for life-long follow-up of these patients., Comparison between different types of diversion should, however, be made with care because of potential confounding by indication.
