Omission of indwelling urinary catheter after robotic partial nephrectomy in female patients: a single-surgeon experience.

To assess the necessity of indwelling urinary catheters in female patients undergoing robotic partial nephrectomy by comparing their outcomes. An IRB-approved, prospectively maintained renal cancer database was reviewed for female patients undergoing robotic partial nephrectomy by a single surgeon at one institution between February 2020 and May 2025. Data was stratified by the use of urinary catheters. The primary outcome was the rate of urinary retention, necessitating the discharge from the hospital with a catheter. Secondary outcomes included perioperative variables. Statistical analysis included Student's t-test and Fisher's exact test.A total of 103 female patients were included (52 patients with a catheter, 51 patients without a catheter). Three patients (2.9%) required discharge with a catheter. Between the groups with and without a catheter, only statistically significant findings were BMI (30.2 vs. 26.9 kg/m2, p = 0.014), length of hospitalization (1.15 vs. 0.92 day, p = 0.007), and surgical approach between multiport and single port robots (p = 0.0021). There were no statistically significant differences in demographic characteristics and perioperative variables between the patients who had urinary retention and the patients who were able to void spontaneously after partial nephrectomy. Omitting a urinary catheter during robotic partial nephrectomy appears feasible in female patients without compromising their outcomes. Routine usage of indwelling urinary catheters should be carefully considered.
