The challenge of pediatric continent urinary diversion

A catheterizable serous-lined urinary outlet associated with the ileal bladder augmentation Abol-Enein and Ghoneim procedure: a safe and reliable procedure in children

Purpose

This study aims to evaluate the long-term outcome of the serous-lined extramural continent catheterizable outlet procedure (SLECCOP) associated with ileal bladder augmentation in children.

Methods

This was a monocentric and retrospective study (2002-2021) that included children (<18 years) undergoing the SLECCOP associated with W-shaped ileocystoplasty with a catheterizable channel (Abol-Enein and Ghoneim procedure). Patients who received other types of bladder augmentation or W-shaped ileocystoplasty without a catheterizable channel were excluded. Patient records were reviewed for demographic information, surgical data, and long-term outcomes.

Results

This study included 52 children [33 boys, median age: 8.5 (0.8-18) years]. Pathological conditions included 28 children with the bladder exstrophy and epispadias complex (BEEC), 11 with neurogenic bladders, and 13 with other pathologies. Two patients underwent total bladder substitution. Thirty-four (65%) patients had bladder neck reconstruction (BNR), with 23 undergoing the SLECCOP and ileocystoplasty and 11 having prior BNR. All stomas, except for two, were umbilical, and were associated with omphaloplasty in 28 patients with the BEEC. A total of 40 stomas were created using the appendix (77%) and 12 with a Monti tube (23%). Stoma-related complications included cutaneous strictures (n = 2, 4%) and leaks (n = 10, 19%), all treated by dextranomer/hyaluronic acid copolymer injection (n = 10). A redo surgery was required in three patients: extraserosal wrapping was performed for persistent leakage (n = 2, 4%), and surgical revision was required for the Monti tube procedure (n = 1, 2%). Three patients (6%) underwent dilatation for transient stoma stenosis. Leakage occurred in 20% of appendix channels (n = 8/40) and 17% of Monti tubes (n = 2/12). Strictures were reported in 3% of appendix channels (n = 1/40) and 8% of Monti tubes (n = 1/12). Bladder stones developed in four patients (8%). Channel leakage persisted in one patient (2%) at a median follow-up of 4.4 years (IQR 1.4-9.7).

Conclusion

W-Ileal bladder augmentation with the SLECCOP is an efficient technique for treating children with incontinence caused by different etiologies. The rate of channel complication is very low, specifically for strictures, in this complex population of patients.

Telenursing Intervention for Clean Intermittent Urinary Catheterization Patients: A Pilot Study

Telenursing is a promising strategy to make nursing care feasible in different health situations, mainly to help patients with chronic illnesses. The aim in this study was to test the feasibility (acceptability and usability) of a telenursing intervention in care delivery to patients using clean intermittent urinary catheterization. This descriptive study focused on an intervention involving urology outpatients. The telenursing intervention was implemented synchronously by audio calls and chat and asynchronously by e-mail as part of a pilot study. The contact between nurse and patient was undertaken through an active search or on spontaneous demand, in which the patient contacted the nurse when necessary. During the 5 weeks of study, 21 telenursing care sessions took place, including 13 (61.9%) on spontaneous demand and eight (38.1%) on active demand. With regard to the technological resource used, 13 telenursing sessions (61.9%) took place by telephone call and eight (30.1%) by e-mail. The pilot study demonstrated the potential of the telenursing intervention to achieve important results, and as a complement to the patients' traditional health treatment. In addition, it revealed various barriers that need to be overcome for this type of care to take place effectively.

Outcomes of revision surgery for difficult to catheterize continent channels in a multi-institutional cohort of adults

INTRODUCTION

The study aimed to describe the strategies of surgical revision for catheterizable channel obstruction and their outcomes, including restenosis and new channel incontinence.

METHODS

We retrospectively queried the charts of adults who underwent catheterizable channel revision or replacement from 2000-2014 for stomal stenosis, channel obstruction, or difficulty with catheterization at the Universities of Minnesota, Michigan, and Utah. The primary endpoint was channel patency as measured by freedom from repeat surgical intervention. Secondary endpoints included post-revision incontinence and complication rates. Revision surgeries were classified by strategy into "above fascia," "below fascia," and "channel replacement" groupings.

RESULTS

A total of 51 patients who underwent 68 repairs (age 18-82 years old; mean 45) were identified who met our inclusion criteria. Channel patency was achieved in 66% at a median 19 months post-revision for all repair types. There was no difference in patency by the type of channel being revised, but there was based on revision technique, with channel replacement and above the fascia repairs being more successful (p=0.046). Channel incontinence occurred in 40% and was moderate to severe in 12%. The type of channel being revised was strongly associated (p=0.003) with any postoperative channel incontinence. Surgical complications occurred in 29% of all revision procedures, although most were low-grade.

CONCLUSIONS

Surgical revision of continent catheterizable channels for channel obstruction can be performed with acceptable rates of durable patency and incontinence; however, the surgeon needs to have experience in complex urinary diversion and familiarity with a variety of surgical revision strategies.

A multi-institutional study of perioperative and functional outcomes for pediatric robotic-assisted laparoscopic Mitrofanoff appendicovesicostomy

BACKGROUND

Robotic techniques are increasingly being used for reconstructive procedures in the pediatric population.

OBJECTIVE

The present study reported the functional and perioperative outcomes of a multi-institutional cohort of pediatric patients who underwent robotic-assisted laparoscopic Mitrofanoff appendicovesicostomy (RALMA).

STUDY DESIGN

Pediatric patients who underwent RALMA at five different centers were included. Positioning is shown (Summary Figure). Demographics were gathered, and intraoperative parameters included concomitant procedures, detrusor tunnel length, estimated blood loss (EBL) and operative time. Perioperative outcomes included length of hospital stay (LOS), morphine use and 30-day complications. Outcomes were reported in terms of stomal continence and surgical revisions.

RESULTS

Eighty-eight patients with a mean age of 10.4 ± 4.0 years were included in the analysis. Median follow-up was 29.5 months (IQR 11.8-45.0). Bladder augmentation was performed concomitantly in 15 (17%) patients, and bladder neck procedures in 34 (39%). Mean detrusor tunnel length was 3.9 ± 1.0 cm, EBL was 54 ± 70 ml, and operative time was 424 ± 120 min. Postoperatively, mean LOS was 5.2 ± 2.8 days. Patients who underwent concomitant augmentation had higher EBL and operative times (both P < 0.05). At 90 days, complications occurred in 26 patients (29.5%) with six Clavien grade ≥3 (6.8%). During follow-up, 11 (12.5%) patients required appendicovesicostomy revision. Regarding functional outcomes, 75 (85.2%) patients were initially continent. After additional procedures, 81 (92.0%) patients were continent at last follow-up.

DISCUSSION

Compared to previous open series, initial stomal continence rates with RALMA were acceptable, with a minority of patients requiring subsequent procedures to manage complications and achieve continence.

CONCLUSION

RALMA is safe and effective in a pediatric population with regard to perioperative complications and stomal continence.

Is continent urinary diversion feasible in children under five years of age?

PURPOSE

To review our clinical experience with urinary continent catheterizable reservoir in children under five years of age.

MATERIALS AND METHODS

A total of 23 patients (16 males, 7 females) with a median age of 3.64 years were evaluated. Among these, 6 (26.08%) had a posterior urethral valve, 9 (39.13%) myelomeningocele, 4 (17.39%) bladder exstrophy, 2 (8.69%) genitourinary rabdomyosarcoma, 1 (4.34%) had spinal tumor and 1 (4.34%) an ano-rectal anomaly.

RESULTS

Perioperative complications were observed in four patients consisting of one febrile urinary tract infection, one partial operative wound dehiscence, one partial stomal dehiscence and one vesico-cutaneous fistula after a secondary exstrophy repair. The overall long-term complications rate was 40.90% and consisted of two stomal stenoses (9.09%), one neobladder mucosal extrusion (4.54%), three neobladder calculi (13.63%) and persistence of urinary incontinence in three patients (13.63%). The overall surgical revision was 36.36% and final continence rate was 95.45% with mean follow-up of 39.95 months

CONCLUSION

Continent urinary diversion is technically feasible even in small children, with acceptable rates of complications.

Complications of the catheterizable channel following continent urinary diversion: their nature and timing

PURPOSE

We reviewed the incidence, nature and timing of complications related to the catheterizable channel following continent urinary diversion.

MATERIALS AND METHODS

We retrospectively reviewed the records of 67 patients who underwent continent urinary diversion at British Columbia Children's Hospital from 2000 to 2006. Catheterizable channels included 54 Mitrofanoff appendicovesicostomies and 13 ileovesicostomies. Medical records were reviewed for predetermined complications and their timing, that is early -12 months or less, or late - more than 12 months.

RESULTS

At a median followup of 28 months (range 3 to 62) a total of 17 complications were identified in 14 patients (21%). Superficial cutaneous stenosis developed in 4 of 67 cases (6%) as an early and as a late complication. These cases were initially treated with operative dilation and surgical revision as necessary. Channel stricture, which developed in 4 of 67 patients (6%) as an early and as a late complication, was treated with operative revision in 2 and endoscopic resection in 2. Three patients (5%) had stomal prolapse, which was generally a late occurrence and required operative revision in all. Channel leakage developed in 6 of 67 patients, presenting as an early complication in 50%. Endoscopic injection of bulking agents was attempted in 4 of these patients and it was successful in 2. Overall 82% of complications were successfully managed by endoscopic or superficial procedures.

CONCLUSIONS

Complications of the catheterizable channel are a frequent and challenging problem. They appear to occur throughout the life of the channel with most developing within the first 2 years. Further followup is required to assess the performance and durability of continent catheterizable channels in children as patients progress to adulthood.
