Novel pelvic immobilization method following bladder exstrophy repair.

We introduce a novel method of pelvic immobilization following bladder exstrophy repair involving a custom-made brace that offers adequate pelvic immobilization with the added benefits of no added operative time, easy evaluation of surgical sites, simplified wound care including sponge bathing, and overall less cumbersome management for the family given its more streamlined size.

Outcomes after dextranomer/hyaluronic acid bladder neck injection in patients with urethral incontinence following bladder neck repair.

INTRODUCTION: Many patients who undergo surgery for bladder neck (BN) incompetence may still experience incontinence postoperatively. Dextranomer/hyaluronic acid (Dx/HA) is widely used for endoscopic treatment of vesicoureteral reflux in children; however, few studies have reported its use in treating incontinence after BN surgery. OBJECTIVE: The aim of this study was to evaluate outcomes after Dx/HA bladder neck injection in patients with persistent outlet incompetency following BN Repair. STUDY DESIGN: We retrospectively reviewed patients at a single pediatric tertiary care center with history of prior bladder neck surgery and reported persistent incontinence who then underwent endoscopic bladder neck Dx/HA injection from 2013 to 2018 and had subsequent follow-up post-injection. We described primary outcomes of reported incontinence as "wet" (leakage similar to before injection), "improved" (wet but leakage improved), and "dry" (no leakage). Our secondary outcome was need for a secondary procedure after Dx/HA injection, including Dx/HA injection or bladder neck closure (BNC). RESULTS: At first follow-up (median 2.3 months post-op), 7/19 were wet, 6/19 were improved, and 6/19 were dry. At last follow-up (median of 34.7 months), only three patients (16%) were dry. Only one patient who received a single surgery for Dx/HA injection was "dry", though nearly 2/3rds (12) were initially "improved" in their continence. Overall, seven patients had another intervention or surgery after first injection. Five patients had multiple Dx/HA injections after first procedure, which resulted in dryness by last assessment in two of these. Four patients (21%) in the overall cohort required subsequent BNC. DISCUSSION: Longer-term follow-up in our study demonstrated that only one patient who received a single procedure of Dx/HA injection remained dry. Several studies had follow up for greater than 1 year after initial bladder neck Dx/HA injection; rates of dryness after a single surgery for injection were variable and reported between 20 and 40% over follow-up times ranging from 1.5 to 7 years (Alova et al., 2012; DaJusta et al., 2013; Lottmann et al., 2006a; Lottmann et al., 2006b; Kitchens et al., 2007). Our st udy does have inherent limitations. This study was performed at a single institution in a retrospective manner, with a single surgeon reviewing the medical record to determine operative techniques and continence outcomes. The patient population is small, although relatively comparable to other previously reported studies. Outcomes were based on documentation of patient reports and are therefore lacking in objectivity. CONCLUSION: In patients with prior unsuccessful BN repair, long-lasting dryness after single Dx/HA BN injection is unlikely, although one-third may demonstrate relatively durable improvement in incontinence.

Caregiver disclosure of common early childhood pediatric urologic surgeries.

BACKGROUND: Certain pediatric urologic diagnoses can have serious long-term adverse health outcomes. As a result, it is important for a child to be aware of their diagnosis and a prior surgery. When children have surgery prior to the age of memory formation, it is incumbent upon their caregiver to disclose this surgery. When and how to disclose this information and even if this occurs, is not clear. OBJECTIVE: We developed a survey to assess caregiver plans to disclose early childhood pediatric urologic surgery and evaluate for predictors of disclosure and resources needed. METHODS: A questionnaire was distributed to caregivers of male children ≤4 years old undergoing single stage repair of hypospadias, inguinal hernia, chordee, or cryptorchidism as part of an IRB approved research study. These surgeries were chosen due to being outpatient surgeries with potential long-term complications and impact. The age criteria was chosen due to likely being before patient memory formation and thus reliance on caregiver disclosure of prior surgery. Surveys were collected the day of surgery and contained information on caregiver demographics, validated health literacy screening, and plans to disclose surgery. RESULTS: 120 survey responses were collected (Summary Table). The majority of caregivers responded affirmatively to planning to disclose their child's surgery (108; 90%). There was no impact of caregiver age, gender, race, marital status, education level, health literacy, or personal surgical history on plans to disclose surgery (p ≥ 0.05). Plan to disclose was also not different across urologic surgery type. Race was significantly associated with being "concerned or nervous about disclosing the surgery to the patient". The median patient age for planned disclosure was 10 years (IQR: 7-13). Only 17 respondents (14%) stated they received any information about how to discuss this surgery with the patient, however 83 (69%) felt this information would be helpful. CONCLUSIONS: Our study suggests that most caregivers plan to discuss early childhood urologic surgeries with children, however want further guidance in how to talk to their child. While no specific surgery or demographic factor was found to be significantly associated with plans to disclose surgery, it is concerning that one in ten patients will potentially never learn about impactful surgery they had as a child. There is an opportunity for us to better counsel our patients' families about surgical disclosure and fill this gap with quality improvement efforts.

Reducing Opioid Prescriptions after Common Outpatient Pediatric Urologic Surgeries: A Quality Improvement Assessment.

Pediatric patients undergoing outpatient surgeries often receive prescriptions for postoperative pain, including opioid medications. As a result, the American Academy of Pediatrics formally challenged all pediatric surgeons to decrease opioid prescribing for common specialty-specific outpatient procedures at discharge. To meet this challenge, we designed a quality improvement project to decrease the average number of opioid doses administered to pediatric patients undergoing 3 common outpatient urologic surgeries: circumcision, orchiopexy, and inguinal hernia repair (IHR). Methods: We formally challenged providers at our institution to reduce opioid doses per prescription and administration to patients overall. We performed a retrospective chart review at our single pediatric institution to establish baseline opioid prescribing values from July 2017 to March 2018. We aimed to reduce this value by 50% in 6 months and sustain this decrease throughout the project duration. Results: We performed 1,518 orchiopexies, 1,505 circumcisions, and 531 IHRs. The percent change in the average number of opioid doses prescribed per patient from baseline values assessed to 2021 was statistically significant for orchiopexies (P < 0.0001), IHRs (P < 0.0001), and circumcisions (P < 0.0001). In addition, the change in the percentage of patients prescribed opioids from baseline was statistically significant for all 3 procedures (P < 0.001). Conclusions: This project demonstrated that through an organized quality improvement initiative, the average number of opioid medications prescribed and the total percentage of patients prescribed opioids following common outpatient pediatric urologic procedures can be decreased by at least 50% and sustained through project duration.

Intraoperative laser angiography in bladder exstrophy closure: A simple technique to monitor penile perfusion.

BACKGROUND: The successful repair of Bladder Exstrophy remains one of the biggest challenges in Pediatric Urology. The primary focus has long been on the achievement of urinary continence. Historically there has been less focus on early penile outcomes. To this end we have incorporated penile perfusion testing using intraoperative laser angiography in to our operative approach. OBJECTIVE: We hypothesize that assessment of penile perfusion at various points in the procedure is a feasible technique that may assist in decision making during the repair of this complex condition. This will reduce the risk of tissue compression and potential loss of penile tissue that has been reported to occur as a complication of the procedure. STUDY DESIGN: Consecutive patients presenting with bladder exstrophy were evaluated at four stages of their operation (i.e. following induction of anesthesia, after bladder mobilization, following internal rotation of the pubis and at the end of the procedure) by infusing indocyanine green (ICG) at a dose of 1 mg per 10 kg body weight. Measurements were taken at 80 s post infusion and the medial thigh served as the reference control. Postoperative penile viability was evaluated by visual inspection and palpation three months following the procedure. RESULTS: Eight consecutive patients were included in this study. Perfusion was easy to measure and posed no significant technical difficulties. Penile perfusion increased slightly following bladder dissection. Internal rotation of the hips with apposition of the symphysis pubis resulted in an average 50% reduction in penile blood flow. Patients undergoing CPRE experienced an additional mean 33% drop in blood flow. In all eight cases the penis was symmetric and healthy with no sign of tissue loss at three months follow up. CONCLUSIONS: This pilot study demonstrates that the measurement of penile perfusion utilizing intraoperative laser angiography is easy to employ and should be considered a reasonable adjunct to tissue assessment in this complex condition. Marked reduction in penile blood flow may occur without any outward clinical signs. Penile perfusion is markedly reduced by apposition of the symphysis pubis and, in the immediate postoperative period, there may be further reduction in penile blood flow with CPRE as opposed to a staged repair. Future correlation with measures of penile viability and function are needed to define the clinical utility of this modality.

Broadening candidate office circumcision patients: A comparison of outcome in children based on age and weight.

INTRODUCTION: Office circumcision with a clamp or Plastibell device is often restricted in practice by patient age and size. This is thought to ensure the patient fits appropriately on the restraining device and limit complications. OBJECTIVE: To compare the outcomes of office circumcision in children ≤3 months of age and ≤5.1 kg in weight to those who do not fit this criterion. STUDY DESIGN: A retrospective chart review was performed of all office circumcisions in children ≤6 months of age performed in our urology clinic between January 2015-August 2018. Patients were divided into two groups: Group 1 (≤3 months old and ≤5.1 kg) and Group 2 (all others). Patient demographics and circumcision technique were recorded. The number of patients with complications and requiring an intervention related to circumcision were compared between groups, as well as the number of patients requiring unplanned hospital visits. Differences in outcomes were evaluated using Pearson's chi-square test. RESULTS: A total of 205 circumcisions were performed in Group 1 and 498 circumcisions were performed in Group 2. All circumcisions were performed by either Gomco clamp or Plastibell device with no significant difference in method between groups (p = 0.5). There was no difference in median follow-up between groups (Group 1: 19 days [IQR 14; 34]; Group 2: 19 days [IQR 14; 36]; p = 0.6). There were no significant differences between groups in the number patients with complications or requiring an intervention (p = 0.08 and p = 0.12, respectively). Significantly more patients in Group 2 required an unplanned hospital visit (p = 0.02) (Table). After categorizing those composing Group 2 into three disjoint sets (children >3 months and ≤5.1 kg, or ≤3 months and >5.1 kg, or >3 months and >5.1 kg), no significant difference across all four groups in regards to complications (p = 0.12) or intervention (p = 0.2) was found. There was a significant difference in unplanned hospital visits (p < 0.001). DISCUSSION: Performing office circumcisions in children outside of age and weight restrictions of ≤3 months and ≤5.1 kg did not significantly increase the risk of complications or need for interventions. Those outside of age and weight restrictions, however, had more unplanned hospital visits. Tailoring parent expectations in this patient group may be needed. CONCLUSIONS: While we found older and heavier children had more unplanned post-procedural related hospital visits, their rates of overall complications and need for subsequent interventions were not significantly higher than younger and lighter children.

Gomco vs. plastibell office circumcision: No difference in overall post-procedural complications and healthcare utilization.

INTRODUCTION: Gomco clamp and Plastibell ring are common methods of office circumcision. While they possess similar features, the Plastibell is retained after the procedure which could impact perceived and true outcomes of the procedure. OBJECTIVE: This study evaluated differences in complications, interventions, and healthcare utilization between Gomco and Plastibell office circumcision techniques. STUDY DESIGN: We retrospectively reviewed urology office performed circumcisions (January 2015-August 2018), limiting analysis to patients with follow-up. Patient demographics and circumcision technique were recorded. Complications, interventions, phone calls, emergency department (ED)/urgent care (UC) visits, and unplanned office visits directly related to the circumcision were recorded. Descriptive statistics for the number of patients experiencing an event and the number of days to event were summarized. Survival analysis with inverse probability of treatment weights was used to estimate hazard and incidence rate ratios (HR and IRR, respectively). RESULTS: 746 patients were included for analysis. Median time of follow-up was 2.7 weeks (interquartile range 2-5). 257 (34%) patients underwent Gomco circumcision; 489 (66%) underwent Plastibell circumcision. The techniques did not significantly differ for complications (HR = 0.9, p = 0.497), interventions (HR = 0.89, p = 0.498), and hospital visits (HR = 1.0, p = 0.985) (Table), although Plastibell patients presented to the ED/UC more (odds ratio = 1.6, p = 0.02). Plastibell patients generated proportionally more post-procedural phone calls (63 vs. 52%), though not significantly (IRR = 1.11; p = 0.426). DISCUSSION: Overall, the type of device used for office circumcision, between Gomco clamp and Plastibell ring, does not appear to impact the outcome of circumcision. Providers should perform the method of office circumcision with which they are familiar and comfortable. There is an overall reliance on healthcare resources suggesting poor family preparation of the post-procedural course regardless of the technique, necessitating better patient education. Limitations of this study include its retrospective nature, variability in follow-up between techniques, and variety of providers, limited to pediatric urologists, performing circumcision. CONCLUSIONS: Gomco and Plastibell office circumcision techniques do not significantly differ in post-procedural complications, interventions, unplanned hospital visits, and office phone calls. Plastibell patients do present more often to the ED/UC perhaps as a result of increased anxiety and perceived immediacy of concerns with the device.

Diagnosis and management of a remnant of the original fistula (ROOF) in males following surgery for anorectal malformations.

PURPOSE: A complication of the surgical management of anorectal malformations (ARMs) is a retained remnant of the original fistula (ROOF) formerly called a posterior urethral diverticulum (PUD). A ROOF may have multiple presentations or may be incidentally discovered during the work-up of ARM after previous surgery. We sought to define the entity and the surgical indications for excision of a ROOF when found. METHODS: We performed a retrospective cohort study of all male patients who presented to our center following previous repair for ARM at another institution, who came for evaluation of problems with urinary and/or fecal continence, from 2014 to 2017. Charts were reviewed for symptoms, original type of malformation, preoperative imaging, treatment, and postoperative follow-up. RESULTS: Of 180 referred male patients, 16 had a ROOF. 14 underwent surgical repair to address this and for other redo indications, and 2 did not require intervention. 13 patients had an additional reason for a redo such as anal mislocation or rectal prolapse. Indications for ROOF excision were urinary symptoms (e.g. UTI, dribbling, passage of mucous via urethra, stone formation), to make a smoother posterior urethra for intermittent catheterization, or for prophylactic reasons. Patients were repaired at an average age of 4.2 years, using a PSARP only approach with excision of the ROOF for all except one patient who needed a laparotomy due to abdominal extension of the ROOF. No patient needed a colostomy. The original ARM repairs of the patients were PSARP (9), laparoscopic assisted (4) and abdominoperineal pullthrough (3). Preoperative evaluation included pelvic MRI, VCUG, and cystoscopy. The ROOF was visualized on 14 of 16 MRIs, 10 of 14 VCUGs, and 14 of 15 cystoscopies. Urinary symptoms associated with a ROOF and ease of catheterization were improved in all repaired cases. CONCLUSION: Patients not doing well from a urinary or bowel standpoint post ARM pull-through need a complete evaluation which should include a check for a ROOF. Both modalities MRI and cystoscopy are needed as a ROOF can be missed on either alone. A VCUG was not reliable in identifying a ROOF. Excision is needed in patients to improve urinary symptoms associated with these lesions and to minimize the small but theoretical oncologic risk present in a ROOF. LEVEL OF EVIDENCE: Level III.

Cloaca reconstruction: a new algorithm which considers the role of urethral length in determining surgical planning.

BACKGROUND: Cloacal malformations represent a uniquely complex challenge for surgeons. The surgical approach to date has been based on the common channel (CC) length with two patient groups considered: less than or greater than 3cm, which we believe is an oversimplification. We reviewed 19 patients, referred after surgery done elsewhere. Eight had postoperative urinary complications, 3 had constant urinary leakage and had been left after surgery with a urethra <1cm, .5 with an original 3 to 5cm common channel, who had undergone total urogenital mobilization (TUM), experienced peri-operative urethral loss needing a vesicostomy, and later, a Mitrofanoff. These patients together with a review of the cloacal and urological literature led us to design a new algorithm where urethral length is a key determinant for care. METHODS: We prospectively collected data on 31 consecutive cloaca patients referred to our team (2014 to 2016) and managed according to this new protocol. The CC length, urethral length, surgical technique employed, and initial outcomes were recorded. RESULTS: Of 31 primary cases, CC length was 1 to 3cm in 20, 3 to 5cm in 9, and greater than 5cm in 2. In the 1 to 3cm and the 3 to 5cm groups, a urethra less than 1.5cm led us to perform an urogenital separation. We only performed a TUM if the urethra was greater than 1.5cm. Using this protocol, we performed a urogenital separation in 1 of 20 in the 1 to 3cm CC group, 6 of 9 in the 3 to 5cm CC group, and 2 of 2 in the greater than 5cm CC group. Seven patients underwent separation, who with the previous approach, would have had a TUM. Thus far, no urinary leakage or urethral loss has occurred in any patient, but follow-up is less than 3years. CONCLUSION: Urethral length appears to be a vitally important component in cloacal reconstruction. A short urethra left after repair can lead to urinary leakage. A TUM done under the wrong circumstances can lead to urethral loss. We describe a new technical approach to cloacal repair which considers urethral length but recognize that long term urological outcomes will need to be carefully documented. TYPE OF STUDY: Clinical cohort study with no comparative group. LEVEL OF EVIDENCE: Level 4.

Spinal anesthesia after intraoperative cardiac arrest during general anesthesia in an infant.

Although generally safe and effective, severe perioperative complications, including cardiac arrest, may occur during general anesthesia in infants. With the emergence of evidence that specific anesthetic agents may affect future neurocognitive outcomes, there has been an increased focus on alternatives to general anesthesia, including spinal anesthesia. We present a case of cardiac arrest during general anesthesia in an infant who required urologic surgery. During the subsequent anesthetic care, spinal anesthesia was offered as an alternative to general anesthesia. The risks of severe perioperative complications during general anesthesia are reviewed, etiologic factors for such events are presented, and the use of spinal anesthesia as an alternative to general anesthesia is discussed.
