Continuous Bladder Irrigation with Saline

Effect of Post-operative Irrigation Nonrandomized comparison of 1592 patients Overall relative risk reduction 31% HR: 0.69 (95% CI, 0.59 – 0.88; p < 0.001) Single instillation: relative risk reduction 35% HR: 0.65; 95% CI, 0.58 – 0.74; p < 0.001. Adjustment for the randomized treatment and EORTC recurrence risk score post-op irrigation reduced the relative risk of recurrence by 21% HR: 0.79 (95% CI, 0.67 – 0.93; p = 0.004).

PSI: No Effect on Progression Sylvester RJ. et al. Eur Urol 2016;69:231 – 244

Alarming Fact: Increased Mortality with PSI Increase in the risk of death by 26% with immediate instillation (HR: 1.26) Sylvester RJ. et al. Eur Urol 2016;69:231 – 244

Drugs Used for Instillation Sylvester RJ. et al. Eur Urol 2016;69:231 – 244

Argument Against Routine Use of PSI PSI is effective only in low risk patients Recurrences (if any) will be small papillary tumors (median size 3 mm) Sylvester RJ. Eur Urol 2016;69:231 – 244 (Strongly recommend a post hoc analysis of SWOG 2018 to find out the median size and grade of recurrences) These can be managed effectively by active surveillance or office fulguration Soloway MS.
