    Abstract Aim: The presentation, and medical and surgical management of all new onset non-congenital hydroceles in boys older than 1 year of age were examined. Of particular interest was the outcome of those patients who presented with a non-communicating hydrocele that developed after the first year of life and was managed conservatively.
    Methods: All patients older than 12 months of age who were evaluated as outpatients with the diagnosis of hydrocele from January 1994 to January 2001 were identified. Possible risk factors and predisposing conditions were determined. For the patients who had surgical correction, surgical indications were identified. For non-surgical patients, long-term outcomes were recorded.
    Results: A total of 302 patients older than 12 months of age with the diagnosis of new onset hydrocele were identified. Of these, 35% were non-communicating, 59% were communicating, and 6% were hydroceles of the spermatic cord. In terms of surgery, 97% of communicating hydroceles, 71% of hydroceles of the spermatic cord, and 34% of non-communicating hydroceles had operative management. Seventy patients with non-communicating hydroceles did not receive surgery and 51 (73%) were contacted for long term follow-up. In these 51 patients, 76% of non-communicating hydroceles resolved completely, 6% decreased in size but were still present, 14% remained the same size, and 4% had an unknown status. The average time to resolution was 5.6 months with a median time of 3 months. The time range to resolution was from 1 day to 24 months. Follow-up averaged 73.7 months with a range of 33 to 120 months.
    Conclusions: Approximately 75% of new onset, non-congenital, non-communicating hydroceles resolve spontaneously irrespective of size. An observation period of 6-12 months would be appropriate prior to repair.

    Abstract Purpose: Unilateral extravesical ureteral reimplantation is comparable to intravesical procedures and more effective than subureteral injection to resolve vesicoureteral reflux. Initial reports showed that the procedure could be feasibly done on an outpatient basis. We present further data on a large series of consecutive, planned, outpatient unilateral extravesical ureteral reimplantations.
    Materials and methods: A total of 250 consecutive patients underwent scheduled outpatient unilateral extravesical ureteral reimplantation. We retrospectively reviewed their records. Patient data were collected on reflux laterality and grade, operative time, hospital stay, complications, need for rehospitalization and resolution rate on radiography 1 month postoperatively.
    Results: A total of 209 females (84%) and 41 males (16%) underwent planned outpatient extravesical ureteral reimplantation, including on the left side in 158 (63%) and on the right side in 92 (37%). Mean reflux grade was 3.2 with grades II to V in 64 (26%), 96 (38%), 74 (30%) and 16 cases (7%), respectively. Average operative time was 63 minutes and average length of stay, defined as time from initial admission in to discharge home, was 6.2 hours (range 3 to 10 hours). Short-term and late complications occurred in 9 (3.6%) and 8 patients (3.2%), respectively.
    Conclusions: Extravesical ureteral reimplantation for unilateral vesicoureteral reflux may be consistently done on an outpatient basis with a reasonable complication rate and a low postoperative hospital admission rate.

    Abstract Objective: To answer the question: 'Is there a learning curve associated with a subureteric injection of Deflux(®)?'
    Materials and methods: We retrospectively reviewed charts of patients who received subureteric injection of dextranomer/hyaluronic acid (Deflux(®){AQ2}) (225 procedures) for treatment of vesicoureteral reflux (VUR) by four surgeons. The study included 55 patients, 82 ureters, who had postoperative follow-up with a voiding cystogram or nuclear medicine cystogram. Exclusion criteria were prior anti-refluxing procedures, duplicated collecting systems, and non-achievement of a negative intraoperative cystogram. Patients were divided into two groups based on whether or not they received an intraoperative cystogram after the injection. The two groups were compared for VUR resolution rates on follow-up imaging.
    Results: Twenty patients underwent an intraoperative cystogram (Group 1, 33 ureters) and 35 did not (Group 2, 49 ureters). The two groups were similar in age, preoperative reflux grade, amount of Deflux injected into each ureter, and time to postoperative studies. In Group 1, 11 ureters (33.3%) and also, in Group 2, 11 ureters (22.4%) had reflux on follow-up imaging.
    Conclusions: There was no improvement in VUR resolution rate following subureteric injection of Deflux(®) when an intraoperative cystogram demonstrated no reflux to be present immediately after injection. Of ureters that did not reflux on intraoperative cystograms, one-third displayed return of reflux on follow-up imaging, which suggests no learning curve and that failures are not likely to be caused by poor surgical technique.

    Abstract Purpose: Unilateral extravesical ureteral reimplantation is comparable to intravesical procedures for resolution of primary vesicoureteral reflux (VUR). Defining whether this operation can be consistently performed on an outpatient basis is important.
    Materials and methods: A total of 80 patients with unilateral VUR were treated with extravesical ureteral reimplantation, of whom 20 were treated on an inpatient basis and 60 on an outpatient basis. We retrospectively reviewed these groups and conducted a telephone survey to evaluate overall patient satisfaction, and pain and nausea on postoperative days 1 and 14.
    Results: There were no significant differences in age, gender, laterality or operative time between the groups. Average length of hospital stay was 31.25 hours (range 20 to 120) for the inpatient group and 6.6 hours (3.25 to 11.20) for the outpatient group. Average intravenous narcotic use in the inpatient group was 0.39 mg/kg, compared to 0.14 mg/kg for the outpatient group (p < 0.005), and included 1.76 mg/kg ketorolac in inpatients and 0.74 ketorolac in outpatients (p < 0.005), and 0.2 mg/kg ondansetron in inpatients and 0.12 mg/kg ondansetron in outpatients (p = 0.004). Four of the 60 outpatients (6.7%) were either hospitalized postoperatively or rehospitalized on postoperative day 1. The results of the survey for the 2 groups were not significantly different.
    Conclusions: Extravesical ureteral reimplantation for unilateral VUR may be performed without compromise in quality on an outpatient basis with significantly less use of intravenous analgesics and anti-emetics.

    Abstract Purpose: We assess the incidence of electrolyte and creatinine changes following unstented bilateral ureteral reimplantation and attempt to identify associated risk factors.
    Materials and methods: A total of 107 consecutive children with bilateral vesicoureteral reflux underwent bilateral unstented ureteral reimplantation. Study exclusion criteria were plication or tapering of any ureter, age less than 1 year and/or baseline serum creatinine greater than twice normal for age. Postoperatively serum electrolytes and creatinine were assessed by venous puncture until values normalized. The presence of nausea, vomiting, urinary retention and oliguria were recorded.
    Results: Of the patients 46 females and 10 males 1.0 to 10.9 years old met the study criteria and had complete data available. Four patients (7.1%) had postoperative potassium greater than or equal to 5.0 mmol/l (range 5.0 to 5.3), including 3 (75%, p = 0.0238) who received potassium supplemented intravenous fluid postoperatively. Eight (14.3%) patients had postoperative creatinine greater than 1 mg/dl (range 1.3 to 2.3) and concurrent hyperkalemia with increased creatinine occurred in 2 (25%, p = 0.0295). Nausea and vomiting beyond postoperative day 1 were noted in 6 patients (75%, p = 0.0122). Neither oliguria nor urinary retention reached statistical significance in correlation with increased potassium and/or creatinine. However, urine retention approached statistical significance in patients with increased creatinine (p = 0.0747). No adverse effects from hyperkalemia were noted.
    Conclusions: Adverse effects from hyperkalemia following unstented bilateral ureteral reimplantation are uncommon. Potassium containing intravenous fluids should be avoided in the early postoperative period. Routine serum electrolyte determination may be helpful in patients undergoing unstented bilateral ureteral reimplantation when persistent nausea, emesis or urinary retention is present.
