Single-system ectopic ureter: a 15-year review.

Abstract. Ectopic ureters present in childhood with symptoms related to an abnormal site or structure (refluxing, obstructed) of the ureteric orifice. The majority drain duplex kidneys. The diagnosis is relatively easy if the poles are functioning or hydronephrotic. Associated malformations are rarely seen and the results of surgery are gratifying. If an ectopic ureter drains a single kidney, it is called a single-system ectopic ureter (SSEU). We reviewed a 15-year experience (1980–1995) with 127 ectopic ureters from our hospital:11 SSEUs in ten consecutive children were managed during this period. Our data lead us to believe that SSEUs are a special subset of ectopic ureters. Diagnosis is often delayed because the ectopic ureter may be associated with a single small, dysplastic, poorly-functioning, non-visualised kidney and the child may be thought to have a contralateral normal ‘solitary kidney’. Associated systemic malformations are common. Residual symptoms of wetting may persist in the early postoperative period. A high degree of suspicion must be maintained for this entity when a child presents with urinary symptoms of wetting or recurrent infection and a “solitary kidney”. Early endoscopic examination of the genitourinary tract will clinch the diagnosis in the majority of cases. Residual symptoms of wetting in the postoperative period generally resolve with passage of time.

Endoscopic placement of double-J ureteric stents in children as a treatment for primary obstructive megaureter

Aim: To determine the efficacy and potential complications of double-J ureteric stents in the treatment of persistent or progressive primary obstructive megaureter in pediatric patients within our institution. Materials and Methods: A retrospective case-note review of all patients with double-J ureteric stents, between 1997 and 2004, was performed. In all, 38 stents were inserted in 31 patients aged between 2 months and 15 years of age. Complications and results of follow-up investigations and the need for follow-up investigations were recorded. Patients were followed up clinically and radiologically for a minimum of 2 years following stent insertion. Results: Endoscopic placement of double-J ureteric stents in childhood is straightforward and complications are uncommon (8/38 insertions). In non-resolving or progressive primary non-refluxing megaureter, double-J ureteric stenting alone is effective with resolution of primary non-refluxing megaureter in 66% of cases (25/38 insertions). Conclusions: Ureteric stenting provides an alternative to early surgery in patients with primary non-refluxing megaureter. The youngest patient in our series was 2 months old at the time of endoscopic ureteric double-J stent insertion. Endoscopic placement of ureteric double-J stents should be considered as a first-line treatment in the management of persistent or progressive non-refluxing megaureter leading to progressive hydronephrosis or pyonephrosis.

Ileocolic ulceration: A long-term complication following ileocolic anastomosis

The long-term complications of loose stools and failure to thrive following resection of the ileocecal region with end-to-end ileocolic or jejunocolic anastomosis are well recognized. We report four cases of a previously undescribed insidious complication that has developed in 8% of our patients after a latent period of many years following the primary operation; that of perianastomotic ulceration leading to severe iron deficiency anemia.

Urinomas protect renal function in posterior urethral valves—a population based study

BACKGROUND/PURPOSE Urinomas have been thought to protect renal function in boys with posterior urethral valves (PUVs), although recent reports have disputed this. This study tested the hypothesis that urinomas protect global renal function in boys with PUV. METHODS A retrospective analysis of all boys with PUV presenting to a tertiary unit derived from a region with an estimated population of 5.5 million was performed. Comparisons of the initial nadir creatinine, current creatinine, and renal status score (RSS) were made between those with and without urinomas. The RSS was derived from nephrology assessment of current renal status (0 = normal to 4 = end-stage renal failure or transplantation). Results were given as median (range), except for RSS, which was given as mean +/- SEM. P < or = .05 was regarded as significant. RESULTS During 1989-2009, 9 of 89 PUV boys were diagnosed with urinomas. Initial nadir creatinine was statistically lower in boys with urinomas (31 [18-44] vs 45 [20-574] mumol/L, P < .01). Length of follow-up was similar (5.1 [2.2-17.3] vs 5.9 [1.8-19.7] years, P = .59). Follow-up creatinine was significantly lower in urinoma boys (44 [25-77] vs 61 [29-1227] micromol/L, P < .05), as was the RSS (0.14 +/- 0.14 vs 0.91 +/- 0.14, P < .01). No urinoma boys progressed to end-stage renal failure or required transplant. CONCLUSION This population-based study of PUV boys demonstrates that urinomas reduce nadir creatinine and significantly protect long-term global renal function.

Central-venous access through the peripheral route in surgical neonates: an audit of 125 consecutive lines from a regional neonatal centre

Abstract A long Percutaneous silastic IV line is frequently used in surgical neonates for infusion of hyperosmolar parenteral nutrition fluid into a central vein for several days without the need for operative insertion of a Broviac catheter or risks of direct puncture of a central vein. Our study was aimed at auditing the performance of 125 consecutive lines over a 2-year period. During this period, insertion was attempted in 125 babies; in 13 cases the line could not be inserted because of technical problems. The gestational ages varied between 25 and 41 weeks and weights between 630 g and 4.2 kg. Success did not appear to be related to the age or weight of the baby. The mean duration of complication-free performance was 22.4 days. There was a significant difference between the complication rate of lines inserted in the operating theatre versus those on the ward (P < 0.05). There was no significant increase in complications in lines used for over 4 weeks. The technique adopted by us for inserting these lines is likely to succeed in the majority of cases, including premature and small-for-dates babies. In our experience, lines inserted in the controlled theatre environment either before or after abdominal surgery performed better. The manufacturers recommendation to electively change the line every 4 weeks needs further prospective evaluation.

Paediatric priapism—treatment conundrum

Priapism is a rare condition in childhood. The majority of reported cases are boys with sickle cell disease, in whom nonoperative management may be successful when patients present early. We report a 14-year-old boy with sickle cell disease who presented with priapism of 72-h duration and was successfully treated by bilateral saphenocorporal shunts.

Bilateral multifocal renal oncocytoma

Renal oncocytoma is a rare benign tumor. Bilateral and multifocal renal oncocytoma has rarely been described in childhood. We report a 12-year-old girl who presented with massive left renomegaly and who was found to have bilateral cystic kidneys. A left nephrectomy was undertaken because of the renal enlargement, the radiological evidence of extensive disease, and to make a diagnosis. A diagnosis of multifocal oncocytoma was made after detailed histological examination.
