“…We previously reported that bladder capacity decreased logarithmically pretransplantation depending on dialysis duration, but exceeded >150 mL at 1 year post‐transplantation, even in extremely small bladders . The prevalence of VUR to the graft was also found to be high in small bladders, and the occurrence of VUR might be associated with pretransplant bladder dysfunction . However, the relationship between bladder dysfunction before transplantation and the occurrence of VUR was not examined in our previous study, because cystometric evaluations were not carried out …”

Cystometric evaluation of recovery in hypocompliant defunctionalized bladder as a result of long‐term dialysis after kidney transplantation

Bladder compliance decreases logarithmically pretransplantation according to dialysis duration. Although the ability of the patients to recover varies, dysfunctions associated with a pretransplant hypocompliant bladder recover to normal ranges after renal transplantation. A pretransplant hypocompliant bladder seems not to be associated with the post-transplant prevalence of urinary complications or vesicoureteral reflux.

“…In the case that renal parenchymal damage is permanent, renal scarring develops. In recent years, it has been necessary not to neglect the bladder-based factors in the development of renal parenchymal scarring (12)(13)(14)(15). The risk factors in terms of development of renal scarring have been defined in studies.…”

Background/aim: In nonmonosymptomatic nocturnal enuresis (NMNE), the incidence of organic abnormality and urodynamic disorder is more frequent than the general population. The aim of this study is to identify urodynamic disorders and renal scarring in children with NMNE. Materials and methods:This study evaluated the urodynamic disorders and renal scarring of a total of 30 patients who were diagnosed with NMNE. A video-urodynamic test and Tc-99m dimercaptosuccinic acid renal scintigraphy were applied.Results: Records of 605 patients who had been diagnosed with enuresis were analyzed, and 215 (33.5%) of them had been diagnosed with NMNE. Thirty patients older than 6 years old with NMNE were included in the study. Detrusor overactivity was identified in 10 patients. Bladder capacity was low in 5 patients and bladder compliance was low in 2 patients. Renal scarring was identified in 1 patient. Unilateral vesicoureteral reflux was found in 4 patients. Conclusion:Bladder function disorder is also a significant risk factor for the development of renal scarring, besides other risk factors. Organic abnormalities are seen more often in patients with NMNE than patients with monosymptomatic nocturnal enuresis, so urodynamic studies should be remembered for patients with NMNE.

“…This treatment has become the preferred therapy at selected centers because it is simple, generally obviates the need for long-term antibiotic prophylaxis, and often eliminates open surgery in selected children, especially in cases of intermediate and high-grade VUR [3]. Success rates of endoscopic therapy may be affected by factors such as anatomic variations, dysfunctional voiding, nephropathy, and ureteral dilatation grade as well as by appropriate application of the surgery technique [4,5,6,7]. In the endoscopic correction of VUR, polytetrafluoroethylene and then bovine collagen and Macroplastique bulking agents have been used as injection materials but have been replaced by dextranomer hyaluronic acid (DxHa) because of complications with their use.…”

PurposeTo evaluate the efficacy of subureteral injection types in patients with middle- to high-grade vesicoureteral reflux (VUR).Materials and MethodsBetween June 1999 and September 2010, subureteral dextranomer was applied at our clinic to 149 patients (214 refluxing ureters) with grades II, III, and IV VUR. Group 1 consisted of 54 patients (80 ureters), and group 2 consisted of 95 patients (134 ureters). The standard subureteric transurethral injection (STING) procedure was applied to group 1, and the modified STING procedure was applied to group 2. A second and if needed a third injection was applied to unsuccessfully treated patients. The mean follow-up period was 2 years. Patients were evaluated by cystography and ultrasonography in the third month of follow-up.ResultsVUR was resolved completely after a single injection in 54/80 ureters (67.5%) in group 1 and in 94/134 ureters (70.1%) in group 2. Overall successes after a second or a third injection were 61/80 (76.2%) and 111/134 (82.8%), respectively. There was a statistically significant difference between the groups only for grade IV reflux following multiple injections (p<0.05).ConclusionsEndoscopic treatment of VUR is a recommended treatment because it is minimally invasive, efficient, and repeatable. Our study confirmed that a modified STING procedure can be an alternative treatment to the standard technique.
