Noninvasive Evaluation of Bladder Bowel Dysfunction and its Extrapolation as Biofeedback Therapy to Train Pelvic Floor Muscles

Aims

This study aimed to evaluate the noninvasive methods to diagnose bladder bowel dysfunction (BBD) and its extrapolation on biofeedback therapy and pelvic floor exercises (PFE) to treat these children.

Settings and Design

A retrospective cohort study at a tertiary care center was conducted between January 2010 and December 2020, on 204 children, aged 4-18 years, arbitrarily divided into two groups-4-12 and 13-18 years.

Subjects and Methods

Details of lower urinary tract dysfunction were recorded as International Children's Continence Society nomenclature. Bowel habits were recorded and functional constipation was graded using ROME IV. The data recorded were urine analysis, a voiding diary, a dysfunctional voiding symptom score, and uroflowmetry with or without electromyography. Ultrasonography, voiding cystourethrogram, and magnetic resonance imaging were done in appropriate cases. Dysfunctional Voiding Severity Score was used to assist the evaluation and outcome. The treatment protocol included urotherapy, uroflow biofeedback, PFEs, prophylactic antibiotics, pharmacotherapy, and treatment of constipation.

Statistical Analysis Used

Statistical analysis was done using SPSS version 26 and paired t-test was used for comparison and calculating P value.

Results

There was a significant improvement in DVSS and uroflow parameters. However, the magnitude of change produced varied among the age groups. Patients who failed to show any clinical benefit were subjected to alternative therapies such as intrasphincteric Botulinum A toxin with or without neuromodulation.

Conclusions

Integrated uroflow biofeedback (IUB) and PFE expedites the recovery by supplementing the effect of urotherapy; hence, this should be offered to all children with BBD.

Preoperative Bladder Bowel Dysfunction Is the Most Important Predictive Factor for Postoperative Urinary Retention After Robot-Assisted Laparoscopic Ureteral Reimplantation via An Extravesical Approach: A Multi-Center Study

Introduction: Postoperative acute urinary retention (pAUR) is a known occurrence after robot-assisted laparoscopic ureteral reimplantation via an extravesical approach (RALUR-EV). We hypothesized that the risk factor of pAUR after RALUR-EV might be similar to that of pAUR after open reimplantation. We aimed at performing a retrospective multi-institutional study to evaluate the risk factors for pAUR after RALUR-EV. Materials and Methods: Perioperative data collected from two tertiary referral hospitals included demographics and perioperative variables such as bladder bowel dysfunction (BBD) status, vesicoureteral reflux (VUR) grade, and laterality. pAUR was defined as the need for urethral catheter replacement after removal of the initial postoperative catheter. Univariate and multivariate analyses were performed to identify risk factors for pAUR. Results: A total of 117 patients with 174 renal units from the 2 hospitals were enrolled in this study. The median age at the time of surgery was 5 (0.3-19) years. Bilateral RALUR-EV was performed in 57 (48.7%) cases. pAUR rate was 3.4% in all patients and 7.0% in 57 patients with bilateral VUR. All four cases of pAUR occurred after bilateral surgery. Univariate analysis showed age (p = 0.037), weight (p = 0.039), height (p = 0.040), and bilaterality (p = 0.037) as risk factors of pAUR. In a multivariate analysis, BBD was the only significant risk factor of pAUR (p = 0.037). Conclusion: Urinary retention after RALUR-EV occurred less frequently when compared with the previously reported open surgery series. pAUR was seen only in bilateral cases in our series. Preoperative history of BBD, but not male gender or length of surgical time, was the only risk factor of pAUR after RALUR-EV.
