Setting A large training hospital in the Netherlands.Population Patients undergoing anterior colporrhaphy.Methods One hundred patients were included. Patients were randomised into two groups. In one group (n ¼ 50), a transurethral catheter was in place for four days post-operatively and removed on the fifth postoperative day. In the other group (n ¼ 50), catheterisation was not prolonged and the catheter was removed the morning after surgery. Residual volumes after removal of the catheter were measured by ultrasound scanning. Where residual volumes of >200 mL were found the patient was recatheterised for three more days. Urinary cultures were taken before removal of the catheter. Six patients were excluded: four in the standard prolonged catheterisation group and two in the not prolonged catheterisation group. Main outcome measures Need for recatheterisation, urinary tract infection, mean duration of catheterisation and hospital stay. Results Residual volumes exceeding 200 mL and need for recatheterisation occurred in 9% in the standard prolonged catheterisation group versus 40% of patients in the not prolonged catheterisation group (OR 0.15, 95% CI 0.045 -0.47). Positive urine cultures were found in 40% of cases in the standard prolonged catheterisation group compared with 4% in the not prolonged catheterisation group (OR 15, 95% CI 3.2 -68.6). Mean duration of catheterisation was 5.3 days in the standard prolonged catheterisation group and 2.3 days in the not prolonged catheterisation group (P < 0.001). Mean duration of hospitalisation was 7 days in the standard prolonged catheterisation group and 5.7 days in the not prolonged group (P < 0.001). Conclusion The disadvantages of prolonged catheterisation outweigh the advantages, therefore, removal of the catheter on the morning after surgery may be preferable and longer term catheterisation should only be undertaken where there are specific indications.

Objective To compare clean intermittent catheterisation with transurethral indwelling catheterisation for the treatment of abnormal post-void residual bladder volume (PVR) following vaginal prolapse surgery.Design Multicentre randomised controlled trial.Setting Five teaching hospitals and one non-teaching hospital in the Netherlands.Population All patients older than 18 years experiencing abnormal PVR following vaginal prolapse surgery, with or without the use of mesh. Exclusion criteria were: any neurological or anxiety disorder, or the need for combined anti-incontinence surgery.Methods All patients were given an indwelling catheter directly after surgery, which was removed on the first postoperative day. Patients with a PVR of more than 150 ml after their first void were randomised for clean intermittent catheterisation (CIC), performed by nursing staff, or for transurethral indwelling catheterisation (TIC) for 3 days.Main outcome measure Bacteriuria rate at end of treatment.Results A total of 87 patients were included in the study. Compared with the TIC group (n = 42), there was a lower risk of developing bacteriuria (14 versus 38%; P = 0.02) or urinary tract infection (UTI; 12 versus 33%; P = 0.03) in the CIC group (n = 45); moreover, a shorter period of catheterisation was required (18 hours CIC versus 72 hours TIC; P < 0.001). Patient satisfaction was similar in the two groups, and no adverse events occurred.Conclusion Clean intermittent catheterisation is preferable over indwelling catheterisation for 3 days in the treatment of abnormal PVR following vaginal prolapse surgery.Keywords Catheterisation, urinary retention, vaginal prolapse surgery.Please cite this paper as: Hakvoort R, Thijs S, Bouwmeester F, Broekman A, Ruhe I, Vernooij M, Burger M, Emanuel M, Roovers J.

Objective To determine patient preferences for clean intermittent catheterisation (CIC) relative to transurethral indwelling catheterisation (TIC) as the treatment of abnormal postvoid residual bladder volume (PVR) following vaginal prolapse surgery.Design Scenario-based preference assessment during face-to-face interview. Setting Teaching hospital.Population A sample of consecutive patients scheduled for vaginal prolapse surgery.Methods Preference for CIC relative to TIC was assessed using written treatment scenarios. Initially, treatment duration was set at 3 days and the risk for urinary tract infection (UTI) was 30% for both interventions. Both treatment duration and UTI risk related to TIC were kept constant. Treatment duration and UTI risk after CIC were varied until patients altered their preference. In this way, the duration of catheterisation and level of UTI risk related to CIC at which patients would prefer CIC to TIC could be determined.Main outcome measures Patients' preference for CIC relative to TIC.Results When both duration of treatment and UTI risk were identical for both interventions, 64% of patients prefer CIC. Ninety-two percent of patients prefer CIC when CIC lasts 3 days but results in a 15% lower risk of UTI. Assuming that CIC results in a 15% risk of UTI, a total of 98 and 99% of patients prefer CIC to TIC when catheterisation with CIC last 2 and 1 day, respectively.Conclusions Most patients with abnormal PVR prefer CIC to TIC. The results of a recent randomised controlled trial showed that CIC resulted in a 2 days shorter catheterisation and more than 20% reduced risk of UTI. These conditions correspond to a preference of 99% of patients for CIC.

Our objectives were to determine the reproducibility, or interobserver agreement, of transvaginal sonographic imaging of the uterus in patients with abnormal uterine bleeding and to identify the effect of observer experience. Transvaginal ultrasound findings of 235 patients with abnormal uterine bleeding were recorded systematically on videotape. Recordings were reviewed by three observers who had different levels of experience, and who were asked to judge the endometrium/uterine cavity and myometrium separately as being normal, abnormal or inconclusive, according to predefined criteria. Reproducibility was expressed by the observed rates of interobserver agreement and by kappa statistics. The differences in agreement between observer pairs were analyzed by means of McNemar's chi 2 test. The observed rates of agreement for the judgement of the endometrium/uterine cavity varied from 0.85 to 0.89, with a kappa value ranging from 0.70 to 0.78 between observers. The judgment of the myometrium resulted in agreement rates of 0.86-0.91 and kappa values of 0.67-0.80. Although the effect of experience was evident, the differences in agreement between observers were not significant (p > 0.01). The reproducibility of the results of transvaginal sonography of the uterus in patients with abnormal uterine bleeding was good. Observations of the endometrium/ uterine cavity with a normal appearance were the most highly reproducible, with the smallest effect of observer experience. This may reduce the need for invasive diagnostic procedures in patients with abnormal uterine bleeding.
