The Effects of Intradetrusor BoNT-A Injections on Vesicoureteral Reflux in Children With Myelodysplasia / 대한배뇨장애요실금학회지

PURPOSE: We retrospectively evaluated the efficacy of botulinum neurotoxin A (BoNT-A) on vesicoureteral reflux (VUR), continence status, and urodynamic parameters in children with myelodysplasia who were not responsive to standard conservative therapy.METHODS: The study included 31 children (13 boys, 18 girls) with a mean age of 9.2±2.3 years (range, 5–14 years) with myelodysplasia, retrospectively. All children were fully compatible with clean intermittent catheterization (CIC) and did not respond to the maximum tolerable anticholinergic dose. All children received an intradetrusor injection of 10 U/kg (maximum, 300 U) of BoNT-A into an infection-free bladder. All patients had VUR (22 unilateral, 9 bilateral) preoperatively. The grade of reflux was mild (grades 1, 2), intermediate (grade 3), and severe (grades 4, 5) in 25, 7, and 8 ureters, respectively.RESULTS: The mean maximum bladder capacity increased from 152.9±76.9 mL to 243.7±103 mL (P<0.001), and the maximum detrusor pressure decreased from 57±29.4 cm H₂O to 29.6±13.9 cm H₂O (P<0.001). After BoNT-A treatment, 16 refluxing ureters (40%) completely resolved, 17 (42.5%) improved, 5 (12.5%) remained unchanged, and 2 (5%) became worse. Of the 31 children with urinary leakage between CICs, 22 (71%) became completely dry, 6 (19%) improved, and 3 (10%) experienced partial improvement.CONCLUSIONS: In children with myelodysplasia, we were able to increase bladder capacity, enhance continence, and prevent VUR by using intradetrusor BoNT-A injections. Although our results are promising, a larger group of long-term prospective studies are warranted to investigate this method of treatment.

Late complications of spontaneous urethral erosion of a malleable penile prosthesis in a young patient

While oral agents are currently suggested for the initial treatment of erectile dysfunction, penile prosthesis implantation (malleable or inflatable) is accepted as a third-line therapy if intracorporeal injection and intraurethral treatment fail as a secondary choice. Urethral erosion of the malleable penile prosthesis is a well-known complication, mostly due to the indwelling catheter. We report a case of urethral erosion of the malleable penile prosthesis after 23 years. The patient was a 45-year-old man without any underlying risk factors. He subsequently underwent a unilateral rod extraction under regional anaesthesia. It appears that urethral erosion of penile prostheses can appear at any time post operation, without any known facilitative factors and in any age group. Furthermore, simple office manoeuvres may not be possible in some patients.

The Relations between Enuresis in Childhood and Nocturnal Polyuria Syndrome in Adult Life / 대한배뇨장애요실금학회지

PURPOSE: The aim of this study, to investigate whether there is any association between enuresis in childhood and nocturnal polyuria syndrome (NPS) in adult life. METHODS: The study consisted of thirty five patients with nocturnal polyuria, and thirty five healthy people without nocturnal polyuria in adult life, were asked to assess their enuresis in childhood. RESULTS: There was a history of enuresis in childhood in 18 (51.42%) of 35 of men with nocturnal polyuria and in 4 (11.42%) of 35 without nocturnal polyuria. Enuresis in childhood was significantly more common in men with nocturnal polyuria than without nocturnal polyuria. The difference was significant (P<0.0001). The prevalence of enuresis in the nocturnal polyuria (51.42%) was more than two-fold higher than reported prevalence in general populations. CONCLUSIONS: The results of this study suggest that the history of enuresis in childhood seems to increase the risk of having NPS in adult life. This relationship should be taken into account in the evaluation of men with complaints from NPS in adult life and the possible common pathophysiology should be considered in the treatment planning.

Idiopathic Retroperitoneal Fibrosis Mimicking a Pelvic Tumor: a Case of Pericystitis Plastica

Retroperitoneal fibrosis was first described in 1905 by Albarran, a French urologist, who performed ureterolysis for ureteral compression produced by the disease. However, this disease became an established clinical entity by Ormond's account in the English literature in 1948. Pericystitis plastica has been used the define an extremely rare type of Idiopathic retroperitoneal fibrosis (IRF) constricting the bladder. In this study, we discussed the recovery of 29-year-old woman with pericystitis plastica who was misdiagnosed as pelvic malignancy or a chronic/subacut pelvic inflammation at the first evaluation.
