Patient-reported urinary outcomes in adult males with congenital colorectal conditions

Does sacral ratio have any impact on success rate of biofeedback therapy in children with lower urinary tract dysfunction?

INTRODUCTION

To evaluate the possible impact of patients' sacral ratios (SRs) on response to biofeedback (BF) therapy in pediatric patients with lower urinary tract dysfunction (LUTD).

MATERIALS AND METHODS

In this retrospective cohort conducted from 2016 to 2018 in our tertiary medical center, we included the medical records of all pediatric patients with LUTD who were nominated for BF due to having abnormal uroflowmetry patterns and simultaneous increase in electromyography (EMG) activity. Ten sessions of weekly animated BF were performed for each patient. All patients underwent a complete urological evaluation, uroflowmetry with simultaneous EMG and post-void residual measurement before and after treatment. SRs were calculated based on plain anteroposterior lumbosacral radiographs. Patients were then divided into normal SR (≥0.74) and low SR (<0.74) and outcomes were compared between them.

RESULTS

Of the total 86 patients included in our study, 48 (55.8%) had a normal SR (≥0.74), while 38 (44.2%) had a low SR (<0.74). Our data revealed that BF therapy significantly improved maximum and average urinary flow rates, urine volume, daytime urinary incontinence, enuresis, urinary urgency and constipation; irrespective of the patients' SRs (all P < 0.001). Our between-groups analyses showed that after the completion of BF, the SR ≥ 0.74 group had significantly higher maximum urinary flow rate (mean difference [95%CI]: 7.7 [5.4, 10.0], P < 0.001) (Figure) and urine volume (mean difference [95%CI]: 49.9 [19.5, 80.4], P = 0.002) and significantly lower diurnal urinary incontinence (4.2% vs. 21.1%, P = 0.020), enuresis (4.2% vs. 18.4%, P = 0.040) and constipation (2.1% vs. 23.7%, P = 0.004) compared to the SR < 0.74 group.

DISCUSSION

SR has been proposed as a reliable indicator of bony pelvis growth and subsequent lumbosacral neurodevelopment. Additionally, larger SR values are associated with better postoperative sphincter function in children with urological and anorectal malformations. Our results demonstrated that after completion of BF, the normal SR group had a significantly better improvement of some of the uroflowmetry indicators and LUTD-associated symptoms compared to the low SR group.

CONCLUSION

Our findings implied that although BF therapy is an efficient treatment for children with LUTD, irrespective of their sacral development; children with enhanced sacral development may benefit from better clinical response, especially in terms of LUTD-associated symptoms.

Urological outcomes in adult females born with anorectal malformation or Hirschsprung disease

INTRODUCTION

Women born with anorectal malformation (ARM) or Hirschsprung disease (HD) may have impaired urologic function resulting in sequelae in adulthood. This study assessed and compared self-reported urinary outcomes in adult females born with ARM or HD to a reference population.

METHODS

This was an IRB approved, cross-sectional study of female-born patients with ARM or HD, who completed surveys between November 2021 and August 2022. Female patients between the ages of 18 and 80 years were included. Lower Urinary Tract Symptom Questionnaires were administered through REDCap and the responses were compared to a reference population using Chi-squared or Fisher's exact tests.

RESULTS

Sixty-six born female patients answered the questionnaires, two of them identified as non-binary. The response rate was 76%. Median age was 31.6 years. The majority were born with cloaca (56.3%), followed by other type of ARMs (28.1%), complex malformation (9.4%), and HD (6.3%). A history of bladder reconstruction was present for 26.6%. Catheterization through a channel or native urethra was present in 18.8%. Two had ureterostomies and were excluded from the analysis. Seven had chronic kidney disease or end-stage renal disease, three with a history of kidney transplantation. Patients with cloaca had significantly higher rates of urinary incontinence, urinary tract infection, and social problems due to impaired urological functioning, when compared to an age-matched reference population (Table 3).

CONCLUSION

This study emphasizes the need for a multi-disciplinary team that includes urology and nephrology following patients with ARM long term, especially within the subgroup of cloaca.

Adult urological outcomes for patients with anorectal malformation

Anorectal malformations (ARM) are rare congenital anomalies characterized by a spectrum of defects resulting in the absence of a normal anal opening with or without fistula. Urogenital involvement is common, and the fistulous tract may terminate in the genitourinary system in males or within gynecological structures in females. Surgical reconstruction occurs early in life and survival of these patients to adulthood is the norm. There has, therefore, been increased focus on their long-term outcomes to better anticipate and treat the sequelae that may impact their health and well-being as this population ages. For urologists, urinary health, sexual function, and fertility outcomes are of particular interest among this population. This article aims to provide a review of urological, sexual, and fertility outcomes for individuals born with ARM with a focus on key issues that may occur later in life to ensure adequate counseling, screening, and treatment.

Long-term risks of childhood surgery

INTRODUCTION

Several patients, who underwent major reconstruction under the care of an experienced pediatric urologist are now, as adults, several years later, appearing with long term problems and complications. This consensus process was undertaken to give an overview of long term consequences (and their management) of urological childhood surgery.

MATERIAL AND METHODS

Several known urologists with experience in life-long follow up and revisional surgery of patients with congenital conditions were asked to review literature and comment based on their experience about several complications of childhood surgery.

RESULTS

Renal impairment, metabolic consequences, bladder stones, Vit B 12 deficiency and recurrent infections are often encountered. Also recurrent ureteric strictures and difficulties with catheterizable channel (both obstruction and incontinence) can be challenging to manage. Specific attention is needed regarding female sexuality and pregnancy. Both the development of malignancies in reconstructed bladders as secondary malignancies need to be taken into account during follow up.

CONCLUSION

Follow up of patients with rare congenital conditions is highly specialized and revisional surgery can be challenging. Therefore, follow up needs to be organized in specialized centers.
