Abstract
OBJECTIVES To compare the safety, effectiveness and patient satisfaction of an intraurethral valve-pump catheter (In-Flow) versus the current standard of care, clean intermittent catheterization (CIC), for females with hypocontractile or acontractile bladder. MATERIALS AND METHODS The study was a multi-centre, prospective, single-arm crossover study. Eligible patients underwent a 1-week In-Flow tolerability trial. Successful patients then continued through an 8-week baseline phase using CIC, followed by a 16-week In-Flow treatment phase, and a final 4-week treatment withdrawal phase. Outcome measures included post-void residual (PVR), Wagner incontinence-specific quality of life (I-QOL), rate of urinary tract infection and adverse events. At study completion, open enrollment was offered. RESULTS A total of 273 women with a mean age of 48.9 years using CIC entered the study in 18 centres under either the original (n=88) or revised protocols (n=185). The revised protocol included the addition of a 1-week tolerability trial. The reasons for the large early withdrawal of subjects (169/273) were mainly related to initial discomfort and leakage. A total of 77 patients completed the In-Flow treatment phase. PVR was comparable during baseline CIC phase and In-Flow treatment phase (20.3 ml vs. 16.1 ml), with significantly improved quality of life (QOL; mean improvement of I-QOL score +25.9; p<0.001). CONCLUSION The In-Flow catheter appears to be a viable alternative to CIC. A subgroup of patients, mainly those unsatisfied with the currently available treatments, was more likely to tolerate In-Flow catheters, and they may achieve enhanced independence and QOL.

Abstract
Intrinsic sphincter deficiency (ISD) is frequently treated with collagen bulking at the bladder neck. The standard material used, Contigen, biodegrades over 3-19 months requiring repeated injections to maintain efficacy. The study objective was to evaluate use of autologous ear chondrocytes for treatment of ISD. Women with documented ISD had harvest of auricular cartilage. Chondrocytes were isolated from the cartilage and expanded in culture and formulated with calcium alginate to form an injectable gel. Thirty-two patients received a single outpatient injection just distal to the bladder neck. Outcome measures included voiding diary, quality-of-life scores, incontinence severity grading, and pad weight testing. Incontinence grading indicated 16 patients dry, and 10 improved at 12 months for a total of 26 of 32 (81.3%) dry and improved after one treatment. Only four patients had a 12-month pad weight test over 2.2 g. Quality-of-life scores improved significantly after treatment. There was a decrease in incontinence impact scores in all categories. The urogenital distress inventory declined for all categories except bladder emptying and lower abdominal pain. Endoscopic treatment of ISD with autologous chondrocytes is safe, effective, and durable with 50 % of patients dry 12 months after one injection. Twenty-six of 32 patients dry or improved at 3 months after the injection maintained the effect at the 12-month visit.

Abstract
RATIONALE AND OBJECTIVES We tested whether testicular torsion could completely damp distal arterial pulsatility, resulting in venous-appearing arterial waveforms. METHODS Progressively increasing testicular torsion was unilaterally produced in five rats. Doppler waveforms of the testicular artery distal to the torsion were obtained as soon as possible after each level of torsion until a complete absence of pulsatility was noted. RESULTS One animal was not studied further after the first 180 degrees of torsion occluded flow. In three of the remaining four animals, the testicular artery resistive index (RI) at baseline (0.51, 0.58, 0.64) was within the range of the normal human intratesticular RI and decreased with increasing torsion, culminating in nonpulsatile, venous-appearing waveforms at high degrees of torsion. CONCLUSIONS Testicular torsion can completely damp arterial pulsatility, resulting in nonpulsatile, venous-appearing arterial Doppler waveforms.

Abstract
OBJECTIVES The perioperative and long-term outcomes of children with vesicoureteral reflux (VUR) treated by cross-trigonal ureteroneocystostomy were ascertained. METHODS One hundred ten consecutive children with VUR who underwent bilateral cross-trigonal ureteroneocystostomy were studied retrospectively. Nineteen children with neurovesical dysfunction or megaureters requiring tapered reimplants were excluded. Outcome parameters of the remaining 91 children consisted of operative time, length of hospitalization, days of Foley catheter drainage perioperative complications, correction of reflux, subsequent morbidity, and parental satisfaction. RESULTS Of 182 renal units, 11 (6%) had grade 0 VUR, 18 (10%) had grade I, 43 (24%) had grade II, 59 (32%) had grade III, 36 (20%) had grade IV, and 15 (8%) had grade V reflux. The mean operative and hospitalization times were 180 minutes and 5.6 days, respectively. No postoperative complications occurred. Three children were lost to follow-up, and the remaining 88 children had an extended mean follow-up in excess of 3 years. Voiding cystourethrogram documented a 98.3% (173 of 176 renal units) success rate. Sixteen children (18%) experienced nonfebrile clinically symptomatic cystitis episodes and 3 children (3%) experienced one febrile episode each. Telephone parental survey of overall surgical experience revealed a 94% very satisfied, 2% satisfied, and 3% dissatisified rate. CONCLUSIONS Cross-trigonal ureteroneocystostomy is a safe and effective technique that is virtually complication free and has high parental satisfaction. The results of this study provide a baseline for comparison of non-operative treatment of reflux as well as laparoscopic and endoscopic techniques.

Abstract
OBJECTIVES To determine the clinical efficacy, safety, and durability of endoscopically injected glutaraldehyde cross-linked (GAX) collagen for the treatment of intrinsic sphincter deficiency (ISD) in women. METHODS Forty-two women with a mean age of 64 years (range, 28 to 88) underwent injection of GAX collagen for ISD. Collagen was injected via a transurethral or periurethral approach. Treatment outcome was based on the change in stress leak point pressures (SLPP) and individual incontinence grades before and after collagen injection. RESULTS With a mean follow-up of 46 months (range, 10 to 66), 83% were cured (n = 17), greatly improved (n = 5), or improved (n = 13), and 17% were unchanged (n = 3) or worse (n = 4). The median number of treatments was 2 (range, 1 to 8). The 22 women greatly improved or cured required a mean of 2.4 collagen injection treatments, whereas the 20 women who were improved, unchanged, or worse had a mean of 4.1 treatments (P = 0.009). The mean amount of collagen injected per patient was 28.3 cc (range, 2.5 to 85). The group of women who were greatly improved or cured had a mean of 17.5 cc of collagen injected, whereas those who were improved, unchanged, or worse had a mean of 39.5 cc injected (P = 0.002). Mean pretreatment SLPPs of women improved, greatly improved, or cured versus the women unchanged or worse were not significantly different (P = 0.015). The 35 women who were improved or cured had a significant increase in mean SLPP of 65.4 cm H2O (P = 0.001) compared to a mean change in SLPP of 14.7 cm H2O in those women who were unchanged or worse (P = 0.038). CONCLUSIONS GAX collagen injection for the treatment of stress urinary incontinence secondary to ISD appears to be safe, effective, and durable; hence, it should be considered the treatment of choice in appropriately selected female patients.

Abstract
We report on a girl with infected perinephric urinoma and myelodysplasia who presented with a febrile urinary tract infection. A complex perinephric fluid collection with internal echoes was found on renal ultrasound, necessitating placement of a percutaneous drainage tube. Initial urodynamic testing after treatment of the infection revealed a noncompliant bladder with an elevated detrusor leak point pressure. Neurovesical dysfunction with elevated leak point pressure is believed to be the cause of urinoma. Clinical presentation, treatment and pathophysiology of this entity are discussed.

Abstract
Angiomyolipomas were found in 42 kidneys in 23 female and 8 male patients at our medical center. Angiomyolipoma was diagnosed by computerized tomography (CT) alone in 55% of the cases, and by a combination of ultrasound and CT in 36%. Nine of 11 patients with bilateral angiomyolipoma had associated tuberous sclerosis. Treatment consisted of observation in 22 patients, selective arterial embolization in 6, partial nephrectomy in 6 and nephrectomy in 8. A total of 17 patients who were observed had tumors smaller than 4 cm. and 4 h had angiomyolipoma of 4 to 10 cm. With a mean followup of 3.8 years, no observation patient had subsequent renal hemorrhage and only 1 (tumor larger than 10 cm.) had radiographic progression. Despite progression, the latter patient remained asymptomatic for 18 years. Selective arterial embolization (3 tumors 4 to 10 cm. and 3 larger than 10 cm.) resulted in preservation of renal function at a mean of 1 year. All patients treated with partial nephrectomy (6 tumors 4 to 10 cm.) maintained stable renal function without recurrence during a mean 4.7-year followup. Similarly, all individuals who underwent nephrectomy (4 tumors smaller than 4 cm., 3 tumors 4 to 10 cm. and 1 tumor larger than 10 cm.) have stable renal function. We recommend renal conservation for patients with renal angiomyolipoma using a strategy of observation for small asymptomatic tumors, partial nephrectomy for moderate size tumors and selective arterial embolization of large tumors not amenable to partial nephrectomy.

Abstract
Five patients 18 to 73 years old underwent auto-augmentation for a small capacity, poorly compliant bladder. The mean operative time and hospital stay were 106 minutes and 6 days, respectively. No postoperative complications occurred. Followup ranged from 12 to 82 weeks. Bladder capacity increased from 75 to 310 cc or 40 to 310%. Compliance also improved in all patients. Three patients had reflux preoperatively, which resolved in 1 and improved in 2. Of 4 patients who were incontinent preoperatively 3 became continent postoperatively and extended the interval between catheterizations. Upper tract function has remained stable. No patient required enterocystoplasty to control bladder pressures.

Abstract
The combination of high spinal cord injury and neurovesical dysfunction can present formidable problems in urological management. The lack of upper extremity function often prevents intermittent catheterization and leads to alternative methods. A total of 23 patients underwent incontinent ileo-vesicostomy in an effort to gain a low pressure bladder and control of urinary soiling: 17 had been previously treated by catheter drainage, 9 had bladder and/or renal calculi, 9 experienced recurrent sepsis, and 7 had urethrocutaneous fistula and total urinary incontinence. Most patients had poorly compliant bladder dysfunction associated in 9 cases with poor urethral continence function. At a mean followup of 45 months (range 3 to 240 months) 22 of 23 patients had a low pressure reservoir with low pressure degrees of urine into a collection device. Complications included stomal stenosis in 3 patients and poor drainage across the ileovesical junction requiring revision in 2. One of these patients ultimately underwent ileal loop diversion. Upper tract function improved or remained stable in all patients.

Abstract
Loss of a ureter in a renal transplant patient often results in transplant nephrectomy. In 1973 we used vesicopyelostomy with the bladder directly sutured to the renal pelvis as a method of reconstruction in 2 renal transplant patients following ureteral loss. These patients have been followed for more than 20 years and both renal allografts have functioned well. The status of these patients and a review of the literature on vesicopyelostomy are presented.

Abstract
A pure seminal vesicle abscess is a rare condition. We report case 7 in the literature and to our knowledge the first patient who has been managed successfully by noninvasive, conservative antibiotic treatment alone. All previously reported cases of seminal vesicle abscesses have been managed with invasive therapy. In 5 cases the seminal vesicle abscess was incised and drained surgically, while in 1 the abscess was drained percutaneously. We describe a patient with a seminal vesicle abscess, review the literature and recommend a more conservative method of management.
