Pediatric pyeloplasty with double J (DJ) stent drainage requires manipulation of the uretero-vesical junction (UVJ) and a second anesthetic for removal. Externalized uretero-pyelostomy (EUP) stents avoid these issues. We report outcomes of laparoscopic and open pyeloplasty with EUP compared to DJ stents in children. We retrospectively reviewed 76 consecutive children who underwent pyeloplasty for ureteropelvic junction (UPJ) obstruction over a 1-year period by 5 pediatric urologists at a single institution. The exclusion criteria included patients with concomitant urological procedures, other urinary drainage strategies, "stentless" pyeloplasty or patients without follow-up data. Based on surgeon preference, 24 patients had a EUP stent and 38 had a DJ stent placed. The mean follow-up was 23.8 ± 10.9 months and 21.1 ± 11.1 months for the EUP and DJ stent groups, respectively (p = 0.32). The mean age was 40 ± 54 months and 80 ± 78 months for the EUP and DJ groups, respective...

Indirect expenses for accessing health care may place significant fiscal strain on Canadian families. Telemedicine alternatives, using email, telephone, and video conferencing, can mitigate such financial burdens by reducing travel and related costs. Our objectives were to assess costs that families incur visiting an outpatient pediatric surgical clinic, and family attitudes toward telemedicine alternatives. A survey was offered pre-consult to all families who attended pediatric urology and general surgery outpatient clinics over a three-month period. A total of 1032 of 1574 families screened participated (66.0%). Less than half (18.5%) of participants traveled over 200km, and 32.9% spent over 4hours in transit, round-trip. The proportion of participants who spent over $50 on travel and ancillary expenses was 33.0%. In 74.0% of families, 1 or more adults missed work. The proportion of families who perceived costs as somewhat high or high was 29.1%. Perceived cost was positively correlated to distance traveled, money spent, and missed work (p<0.01). Most were comfortable with medical communication using technology; and 34.3%-42.7% would avoid an in-person clinic visit utilizing email, telephone, and video conferencing. Higher perceived cost (p<0.001) and distance traveled (p<0.01) were only weakly associated with greater willingness to substitute a clinic visit with video conferencing. Many families face high costs related to routine outpatient clinical visits, and there is a substantial willingness by them to access telemedicine alternatives, rather than the traditional face-to-face clinical visit.

Advances in the management of Wilms' tumor have been dramatic over the past half century, not in small part due to the institution of multimodal therapy and the formation of collaborative study groups. While different opinions exist in the management of Wilms' tumors depending on where one lives and practices, survival rates have surpassed 90% across the board in Western societies. With more children surviving into adulthood, the concerns about morbidity have reached the forefront and now represent as much a consideration as oncologic outcomes these days. Innovations in treatment are on the horizon in the form of potential tumor markers, molecular biological means of testing for chemotherapeutic responsiveness, and advances in the delivery of chemotherapy for recurrent or recalcitrant tumors. Other technological innovations are being applied to childhood renal tumors, such as minimally invasive and nephron-sparing approaches. Risk stratification also allows for children to f...

We examined the presentation, diagnosis and management of radiologically detected pediatric urachal anomalies and assessed the risk of malignant degeneration. Our radiology database (2000 to 2012) was queried for all children younger than 18 years who were diagnosed with a urachal anomaly radiographically, and the operative database was used to determine those who underwent excision. Data collected included demographics, presenting symptoms, imaging modality and indication for excision. These data were compared to the Ontario Cancer Registry to determine the risk of malignancy. A total of 721 patients were radiographically diagnosed with a urachal anomaly (667 incidentally), yielding a prevalence of 1.03% of the general pediatric population. Diagnoses were urachal remnants (89% of cases), urachal cysts (9%) and patent urachus (1.5%). Ultrasonography was the most common imaging modality (92% of cases), followed by fluoroscopy/voiding cystourethrography (5%) and computerized tomograph...

Botulinum toxin A's (Onabotulinum toxin A - OnabotA) utility in the pediatric population is evolving, and is currently being used in the treatment of lower urinary tract dysfunction, both in children with neuropathic compromise, and non-neuropathic overactive bladders. The results of having OnabotA injected directly into the bladder wall cystoscopically are: a more compliant bladder with reduced bladder pressure, avoiding renal compromise and upper urinary tract deterioration; increased bladder capacity; and the ability for children to reach an improved degree of urinary continence through a minimally invasive approach. A growing body of research in patients with either neuropathic bladders or overactive bladders (OAB), have shown excellent results when looking at urodynamic parameters, patient satisfaction and improvement in symptomatology. One of the main indications for the use of OnabotA in children with neuropathic bladders is to delay or avoid the need for augmentation cystoplasty. By achieving the aforementioned results, some children can delay or avoid this more invasive and permanent procedure. Prospective studies are needed to answer questions regarding optimal dosage and frequency, ideal patient selection criteria and assessment of long-term outcomes and complications.

ABSTRACT Purpose: The management of undescended testes in patients with gastroschisis remains controversial. We reviewed the incidence, natural history, and management of patients with cryptorchidism and gastroschisis. Methods: Male neonates admitted to two pediatric referral centers between January 2001 and December 2007 with gastroschisis were reviewed. Testis location at birth was recorded, and outcomes for those with undescended testes were analyzed. Results: 126 males with gastroschisis were identified and 21 (16.7%) had cryptorchidism affecting 27 testes. In this group, the mean gestational age was 34.2 weeks, mean birth weight was 2330 grams, and 57.1% underwent vaginal delivery. All patients had an initial watch-and-wait approach without orchidopexy at the time of gastroschisis closure. Follow up data was collected on 15 of the 21 patients, totaling 20 cryptorchid testes. Seven of the 20 cryptorchid testes (35%) descended spontaneously. Of the 13 (65%) that remained undescended, 11 (84.6) underwent orchidopexy at a mean age of 25.7 months and 2 (15.4%) required orchiectomy due to testicular atrophy. In two cases, the testicle was intraabdominal. Eight testes found extraabdominally at birth were repositioned into the abdomen before gastroschisis closure. Of these testes, 3 spontaneously descended, 3 required orchidopexy, 1 required orchiectomy, and 1 was lost to follow up. Conclusion: These data suggest that most cryptorchid testes in patients with gastroschisis will not descend spontaneously and 90% of testes were viable at follow-up. Testes that are located extraabdominally at birth have slightly worse outcomes. If feasible, orchidopexy or repositioning of the testes into the inguinal canal should be considered at the time of gastroschisis repair, especially in those that are initially extraabdominal.

Previous data suggest a potential relationship between inflammation and erectile dysfunction. If it is causal, nonsteroidal anti-inflammatory drug use should be inversely associated with erectile dysfunction. To this end we examined the association between nonsteroidal anti-inflammatory drug use and erectile dysfunction in a large, ethnically diverse cohort of men enrolled in the California Men's Health Study. This prospective cohort study enrolled male members of the Kaiser Permanente managed care plans who were 45 to 69 years old beginning in 2002. Erectile dysfunction was assessed by questionnaire. Nonsteroidal anti-inflammatory drug exposure was determined by automated pharmacy data and self-reported use. Of the 80,966 men in this study 47.4% were considered nonsteroidal anti-inflammatory drug users based on the definitions used and 29.3% reported moderate or severe erectile dysfunction. Nonsteroidal anti-inflammatory drug use and erectile dysfunction strongly correlated with age with regular drug use increasing from 34.5% in men at ages 45 to 49 years to 54.7% in men 60 to 69 years old with erectile dysfunction increasing from 13% to 42%. The unadjusted OR for the association of nonsteroidal anti-inflammatory drugs and erectile dysfunction was 2.40 (95% CI 2.27, 2.53). With adjustment for age, race/ethnicity, smoking status, diabetes mellitus, hypertension, hyperlipidemia, peripheral vascular disease, coronary artery disease and body mass index, a positive association persisted (adjusted OR 1.38). The association persisted when using a stricter definition of nonsteroidal anti-inflammatory drug exposure. These data suggest that regular nonsteroidal anti-inflammatory drug use is associated with erectile dysfunction beyond what would be expected due to age and comorbidity.
