“…These agents create a buttress beneath the ureteral orifice and form a flap valve mechanism which prevents reflux during bladder filling [46]. Among the different agents that have been studied, polytetrafluoroethylene is most commonly used, achieving success rates of up to 85% in correcting reflux [47]. Reports of migration of polytetrafluoroethylene particles to brain and lungs, eliciting a granulomatous reaction have been noted [48].…”

Recurrent Urinary Tract Infections in Kidney Transplant Recipients

Urinary tract infections (UTIs) are the most common infectious complication after kidney transplantation (KT). Recurrent UTIs after KT can contribute to increased morbidity and may also be associated with graft loss and mortality. Though several risk factors like female gender, diabetes mellitus, presence of ureteric stents, native kidney disease with urological malformations and re-transplantation have been associated with recurrent UTIs after KT, vesicoureteric reflux appears to be a unique risk factor in this patient population. The emergence of drug-resistant pathogens as causative agents for post-transplant recurrent UTIs poses a significant therapeutic challenge. The use of pathogen-specific antibiotic therapy guided by culture and sensitivity data is warranted. The optimal duration of antimicrobial therapy for recurrent UTIs in renal transplant recipients remains uncertain.

“…PTFE, the first material to be used, is associated with cure rates of 44% to 90% after one implantation, and 66% to 94% after subsequent implantations in children [21]. There is no evidence of long-term deterioration among patients cured of VUR [25]. PTFE is not biodegradable, however, and there is a resultant risk of granuloma formation wherever it accumulates [26].…”

Vesicoureteral reflux: A new treatment algorithm

2002

Vesicoureteral reflux (VUR) affects about 1% of all children and carries an increased risk of pyelonephritis and long-term renal impairment. There are several approaches to the treatment of VUR: antibiotic prophylaxis (conservative treatment), open surgery, and endoscopic treatment. For many patients, endoscopic treatment cures VUR with a single procedure, eliminating the need for long-term antibiotic treatment and avoiding the trauma of a major surgical procedure. The choice of material for endoscopic treatment is of key importance, and, until recently, all available materials were associated with concerns regarding safety and efficacy. Emerging data demonstrate that dextranomer/hyaluronic acid (Dx/HA) copolymer has good long-term safety and efficacy in treating VUR. A new treatment algorithm is, therefore, proposed, recommending that most children with persistent VUR (longer than 1 year) be offered endoscopic treatment with Dx/HA copolymer as an alternative to prolonged antibiotic prophylaxis or open surgery.

“…Because of its simplicity and minimally invasive nature, endoscopic subtrigonal injection methods have recently received some attention as well. Experience with the use of Teflon (subureteric Teflon injection, or STING) in 4126 European children has shown cure of reflux, with only one injection in 76% of the 6216 ureters injected [51]. Others have demonstrated similar results [52,53].…”

“…Although most failures or recurrences are easily remediable by additional injections [51], there is evidence that the STING procedure is not quite as efficacious in VUR grades IV and V [54]. Furthermore, the recurrence rate (approximately 10%) [54,55] is significant, and mandates continued patient evaluation.…”

A transperitoneal laparoscopic approach to endourology

Although endoscopic methods have become the preferred means of management for many diseases facing the genitourinary surgeon, a laparoscopic approach might be considered comparable or advantageous in select circumstances. In the literature, laparoscopists reporting their work have favored the transperitoneal approach; however, there are clear advantages and disadvantages to both transperitoneal and retroperitoneal laparoscopy. Intracorporeal suturing remains the most time-consuming aspect of reconstructive surgery, and research emphasis has been on suturing devices and novel anastomotic techniques. Laparoscopic pyeloplasty is efficacious and should be considered, particularly in the case of a capacious renal pelvis, crossing vessel, or failed previous endopyelotomy. Laparoscopic pyelolithotomy is uniquely suitable for patients with aberrant anatomy, such as a horseshoe kidney, and may be performed concurrently with pyeloplasty for ureteropelvic junction obstruction. The use of laparoscopic extravesical ureteral reimplantation awaits further development in both open and subtrigonal injection techniques. Its use in colposuspension is undetermined and requires further study as suturing technology improves. During laparoscopic exploration, it is possible to address intraoperative injuries to the ureter and bladder laparoscopically. In summary, laparoscopic surgery of the urinary tract is a "work in progress," but it offers promise for some of the most challenging of circumstances. As the technology advances and the clinical experience widens, the indications and contraindications for these techniques will be better established.
