Parents' awareness and knowledge of testicular torsion: A cross-sectional study.

BACKGROUND: Testicular torsion (TT) is one of the most common emergencies in pediatric urology. Family awareness of this condition could lead to early diagnosis and intervention and salvage of the effected testicle. The purpose of this study is to assess parental awareness about TT and their source of knowledge. We also evaluated the response of the parents to their children's scrotal pain. METHODS: A quantitative, observational, cross-sectional study was conducted from March 2017 to September 2017 at our institution. The study target were parents attending the pediatric urology clinic and the comparison group included parents attending the general pediatric clinic in the same period. We distributed a questionnaire and then compared the results in both groups. RESULTS: A total of 200 parents participated in this study (100 parents from each clinic). Nineteen percent of pediatric urology clinic parents were aware and 14% of general pediatric clinic parents were aware about TT with no statistically significant difference observed (P = 0.341). The parents in urology clinic choose doctor as their main source of knowledge (42.1%), while in general pediatric clinic, doctor and through a friend as the main source of knowledge had the same percentage (28.6%). Response of the parents to their children's scrotal pain during working hours in urology and general pediatric clinics was to drive their children to the emergency room immediately with 85% and 82%, respectively. The response of the parents after working hours in both clinics did not show difference, with 83% of parents in pediatric urology clinic and 85% in general pediatric clinic driving their children immediately to the emergency room. CONCLUSION: TT in boys is a common problem we face as pediatric urologists and it may lead to testicular loss if not diagnosed and treated early. We found that the awareness of TT in children is low in our community and it is our responsibility to raise it to improve our children's well-being.

Biofeedback as single first-line treatment for non-neuropathic dysfunctional voiding children with diurnal enuresis.

INTRODUCTION: Non-neurogenic dysfunctional voiding (NDV) accounts for a significant portion of pediatric urology outpatient clinic visits. Biofeedback (BF) is a promising, non-invasive modality for treating children with DV and daytime wetting. Our objective was to investigate BF's efficacy as a single first-line treatment for children with NDV and diurnal enuresis. METHODS: A retrospective cohort study was conducted with a total of 61 consecutive patient records from January 2009 to March 2016. All children with NDV who had BF as first-line treatment were included. Full urological histories, physical examinations, dysfunctional voiding symptom score (DVSS), urine analysis, ultrasound (US), and uroflowmetry (UFM), and electromyogram (EMG) were performed and recorded for all patients before and after finishing the last BF cycle. The patient's satisfaction scale was also obtained. RESULTS: The mean age was 10±2.6 years. Most patients (80.3%) were females. The presenting symptoms were diurnal enuresis, urinary tract infections, and voiding discomfort in 52 (85.2%), 16 (26.2%), and 38 (62.3%) patients, respectively. Six months after the last BF cycle, there was a statistically significant objective improvement in US and UFM+EMG findings with the disappearance of EMG signals in 40 of 61 (65.5%) patients. There was also a significant subjective symptomatic improvement, as the mean DVSS had decreased from 14 to 7.9 (p=0.003). Forty-seven patients (77%) were satisfied, while only eight (13.1%) were not. CONCLUSIONS: BF is considered a potentially effective, single first-line treatment modality for children with DV and diurnal enuresis. Long-term outcome assessments are needed to assess the children's compliance and symptom recurrence.

Utilization of scrotal orchidopexy for palpable undescended testes among surgeons.

INTRODUCTION: Scrotal orchidopexy for palpable undescended testicle (UDT) has received attention in the last decade due to its lower morbidity. This study was conducted to determine the frequency and factors related to the use of the scrotal approach in the surgical treatment of palpable UDT among surgeons. METHODS: An observational cross-sectional study was carried out using an online survey, which was sent to different pediatric urologists, pediatric surgeons, and urologists groups. The survey consisted of questions on demographics as well as surgeons opinions and experience toward scrotal orchidopexy. RESULTS: Of 163 respondents, 57 (35.0%) were pediatric surgeons, 98 (60.1%) were pediatric urologists, and 8 (4.9%) were urologists. There were 86 respondents (52.8%) who used the scrotal orchidopexy approach for UDT at any time in their practice. Pediatric urologists tended to use the scrotal orchidopexy approach for UDT more significantly than others (P < 0.001). There were significantly more scrotal orchidopexies for UDT performed by the pediatric urologists throughout their practice and per year compared to others, respectively (P < 0.001). Fifty-two respondents (31.9%) claimed that scrotal orchidopexy is not a good option for their patients, while seven respondents (4.3%) claimed that the procedure was hard to perform. DISCUSSION: Based on the results of this study, we believe that there is a discrepancy in the reported advantages and success rate of scrotal orchidopexy in the published literature and the utilization of such an approach among surgeons managing palpable UDT in children. CONCLUSION: Scrotal orchidopexy is an underutilized approach in the management of palpable UDT in children. Only 52.8% of our respondents used it for UDT. One of the main reasons why scrotal orchidopexy is underutilized is due to the surgeons' perception that scrotal orchidopexy is not the procedure of choice for their patients and their unfamiliarity with the procedure.

Outcomes of a minimally invasive surgical approach to manage persistent high-grade vesicoureteric reflux post successful augmentation cystoplasty of patients with non-compliant bladder.

INTRODUCTION: Secondary vesicoureteric reflux (VUR) is a common problem associated with non-compliant bladders. Management of this disorder is debatable in literature. Many authors reported high resolution rate of VUR with augmentation cystoplasty (ACP) alone. Others showed significant residual VUR after ACP and recommend ureteric re-implantation (UR) at time of augmentation. OBJECTIVE: Studying efficacy of endoscopic correction of persistent high-grade VUR (ECVUR) post successful ACP. DESIGN: Patients with non-compliant bladders and high-grade VUR are enrolled in the program of our institute, where they are initially managed conservatively. Those not responding are managed endoscopically using intravesical botulinum toxin A and ECVUR. Patients who are not candidates or failed this approach undergo ACP without UR. A total of 82 patients with non-compliant bladder underwent ACP between 2001 and 2011. Of those, 24 patients had high-grade VUR with 44 refluxing units (RU), 20 bilateral and 4 unilateral. The mean age at intervention was 7.62 years with a mean follow-up of 5.6 years. Patients with persistent high-grade VUR and recurrent breakthrough febrile UTI despite antibiotic prophylaxis following ACP were identified and enrolled in our prospective trial of interval ECVUR. Statistical analyses was performed to identify predictors of high-grade VUR resolution after ACP and ECVUR. A p value <0.05 was considered statistically significant (Table 1). RESULTS: Of the 24 patients, 17 underwent ileocystoplasty and 7 underwent ureterocystoplasty. One of the patients that underwent ileocystoplasty found to have a blind ending RU that was excised. Of the 36 remaining RU, 21/36 (58.3%) showed complete resolution in the first follow-up cystogram, and 1 showed complete resolution after 1 year. Two patients, each with single RU, received repeat ACP because of poor compliance and/or inadequate bladder capacity post ureterocystoplasty and showed complete resolution of reflux post-operatively, which increased the resolution rate post ACP to 66.6% (24/36) (Table 2). Of the remaining 12 RU in 7 patients, 10 underwent trial of ECVUR. VUR resolved in 8 RU after the first trial and in another 2 after the second trial (Table 3). Parents of 1 patient with the remaining 2 RU preferred to continue with conservative management (Table 2). DISCUSSION: VUR in patients with non-compliant bladder is usually secondary to high detrusor pressure, low compliance and small capacity. Whereas some investigators showed high resolution rate of VUR post augmentation without UR, claiming that by successfully augmenting the bladder, compliance will increase, detrusor pressure will decrease, and as a result, VUR will spontaneously resolve. Others showed high incidence of persistent VUR (47-57%) and recommend UR at time of ACP. In our study, the incidence of spontaneous resolution was 66.6% (24/36). In cases where VUR persists, ECVUR was performed. With this approach, VUR resolution increased to 94% (34/36). This study is limited by the small number of patients, lack of randomization and lack of comparison group in which patients undergo ACP with UR. CONCLUSION: ACP without UR with interval endoscopic management seems to be an effective and adequate treatment for high pressure, non-compliant bladder as well as high-grade VUR when conservative management fails.

Peristeen anal irrigation as a substitute for the MACE procedure in children who are in need of reconstructive bladder surgery.

INTRODUCTION: We evaluate the efficacy of the Peristeen (Coloplast A/S, Kokkedal, Denmark) transanal irrigation (TAI) system, as a stool cleansing mechanism, to gain stool continence in children who need reconstructive bladder surgery and have fecal incontinence. METHODS: We prospectively evaluated children with neuropathic bladder and bowel dysfunction who were intended for reconstructive bladder surgery and the Malone antegrade continence enema (MACE) procedure. All patients were started on the Peristeen TAI system at least 3 months before surgery to assess their response. Each patient's bowel function, frequency of using the system, satisfaction (and that of their parents) and diaper independency were evaluated before and after reconstructive surgery. RESULTS: We included 18 patients (11 female, 7 male) who were evaluated from April 2006 to the present. The mean age of the group was 7.6 years (range: 4-15). Fifteen patients (83.3%) showed complete dryness from stools. Of the 15 patients, 8 (53.3%) were able to be diaper-free, while 6 continued wearing diapers due to fear of soiling and 1 due to urinary incontinence. The patients underwent reconstructive bladder surgery and continued to use the Peristeen TAI system with the same results postoperatively. The main limitation of this study is the small number of patients included, although this is a very specific patient group. CONCLUSION: Our initial results suggest that the Peristeen TAI system is a successful conservative substitute for the MACE procedure in children who require reconstructive bladder surgery.

Uronephrological outcomes of patients with neural tube defects. Does a spina bifida clinic make a difference?

OBJECTIVE: To review the uronephrological outcomes of myelomeningocele (MMC) patients attending a Spina Bifida Clinic. METHODS: We retrospectively reviewed the medical records of all patients from the combined Spina Bifida Clinic, at King Khalid University Hospital, Riyadh, Saudi Arabia between 1999 and 2009 who had at least one year of follow-up with us. We examined their demographic data, uronephrological status at presentation, most recent follow-up, and the rate of surgical intervention. RESULTS: During the 10-year period, 188 patients were actively followed-up. The mean age at presentation was 5.3 years +/- 3.6 SD. At their last follow-up, 109 patients (58%) were using clean intermittent catheterization, 44 (23%) had received Botox injections, and 26 (14%) had undergone bladder reconstruction. Most (66%) patients were older than 3 years when they presented to us; this group had a significantly higher rate of surgical intervention (Botox or reconstruction) compared with those who came to us earlier (p=0.003 for patients receiving Botox injections, and p=0.025 for patients undergoing bladder reconstruction). CONCLUSION: Our multidisciplinary Spina Bifida Clinic is an integral part of MCC management to reach a safe urological outcome. Early presentations to our clinic resulted in a lesser need for surgical intercession compared with those who presented at more than 3 years old.

Endoscopic correction of vesicoureteral reflux in children with a solitary kidney: the risk of obstruction.

PURPOSE: We aimed to review patients with a solitary kidney and ipsilateral vesicoureteral reflux (VUR) who underwent endoscopic correction of VUR (ECVUR) and to evaluate the prevalence of obstruction in this group of patients. MATERIALS AND METHODS: We retrospectively reviewed the files of all patients who underwent ECVUR at our center between January 2000 and June 2011. Only patients with a solitary kidney and ipsilateral VUR were included. RESULTS: Thirteen patients met our criteria. Two patients (15.38%) developed obstruction post-ECVUR. Both patients developed anuria in the first 24 h after surgery and required intervention. Two patients (15.38%) had increasing hydroureteronephrosis that was discovered on follow-up ultrasound, with no symptoms or signs of obstruction. Both were managed conservatively. CONCLUSION: Our results showed a higher percentage of obstruction post-ECVUR in patients with a solitary kidney (15.38%), who required immediate intervention. Thus, we recommend giving clear instructions to parents of patients with VUR and a solitary kidney post-ECVUR before discharge from the hospital regarding decreased urine output and loin pain. We recommend a follow-up ultrasound to rule out obstruction and detect new-onset hydronephrosis.
