Can preoperative vitamin D level be a predictive factor for continence after radical prostatectomy?

Area of Science:

• Urology
• Endocrinology
• Nutritional Science

Background:

• Post-prostatectomy incontinence (PPI) is a common complication following robotic radical prostatectomy.
• The role of vitamin D in the recovery of urinary continence after prostatectomy is not well understood.
• Investigating potential biomarkers for PPI is crucial for patient management.

Purpose of the Study:

• To examine the relationship between serum vitamin D levels and the development of post-prostatectomy incontinence.
• To determine if vitamin D levels can predict urinary continence status after robotic radical prostatectomy.

Main Methods:

• Retrospective study of 318 patients undergoing robotic radical prostatectomy.
• Serum vitamin D levels measured three months pre-operatively.
• Continence status assessed at 1, 3, 6, and 12 months post-operatively.
• Propensity score matching used to control for confounding factors like age, BMI, and prostate volume.

Main Results:

• Post-prostatectomy incontinence (PPI) rate was 14.5% in the cohort.
• After propensity score matching, significantly higher serum vitamin D levels were observed in continent patients compared to incontinent patients at 1, 3, and 6 months post-operatively.
• No significant difference in vitamin D levels was found at the 12-month mark.

Conclusions:

• Serum vitamin D levels may serve as an important marker for early continence recovery after radical prostatectomy.
• Maintaining adequate vitamin D may support regaining urinary continence in the initial postoperative period.
