Vesicostomy button: how is it placed, in whom, and how is quality of life affected?

ABSTRACT Purpose The vesicostomy button has been shown to be a safe and effective bladder management strategy for short- or medium-term use when CIC cannot be instituted. This study reports our use with the vesicostomy button, highlighting the pros and cons of its use and complications. We then compared the quality or life in patients with vesicostomy button to those performing clean intermittent catheterization. Materials and Methods Retrospective chart review was conducted on children who had a vesicostomy button placed between 2011 and 2015. Placement was through existing vesicostomy, open or endoscopically. We then evaluated placement procedure and complications. A validated quality of life questionnaire was given to patients with vesicostomy button and to a matched cohort of patients performing clean intermittent catheterization. Results Thirteen children have had a vesicostomy button placed at our institution in the 4 year period, ages 7 months to 18 years. Indications for placement included neurogenic bladder (5), non-neurogenic neurogenic bladder (3), and valve bladders (5). Five out of 7 placed via existing vesicostomy had leakage around button. None of the endoscopically placed buttons had leakage. Complications were minor including UTI (3), wound infection (1), and button malfunction/leakage (3). QOL was equal and preserved in patients living with vesicostomy buttons when compared to CIC. Conclusion The vesicostomy button is an acceptable alternative to traditional vesicostomy and CIC. The morbidity of the button is quite low. Endoscopic insertion is the optimal technique. QOL is equivalent in patients with vesicostomy button and those who perform CIC.

Development and evaluation of a training model for paracentetic suprapubic cystostomy and catheterization

OBJECTIVES: Minimally invasive paracentetic suprapubic cystostomy is a technique that should be learned by all surgical trainees and residents. This study aimed to develop a self-made training model for paracentetic suprapubic cystostomy and placement of the suprapubic catheter and then to evaluate its effectiveness in training fourth-year medical students. METHODS: Medical students were divided into an experimental group receiving comprehensive training involving literature, video, and model use and a control group receiving all the same training protocols as the experimental group except without hands-on practice using the model. Each student's performance was video-recorded, followed by subjective and objective evaluations by urology experts and statistical analysis. RESULTS: All students completed the surgical procedures successfully. The experimental group's performance scores were significantly higher than those of the control group (median final performance scores of 91.0 vs. 86.8, respectively). Excellent scores were achieved by more students in the experimental group than in the control group (55% vs. 20%), and fewer poor scores were observed in the experimental group than in the control group (5% vs. 30%). CONCLUSIONS: Based on its cost-effectiveness, reusability, and training effectiveness, this paracentetic suprapubic cystostomy training model is able to achieve goals in teaching practice quickly and easily. Use of the model should be encouraged for training senior medical students and resident physicians who may be expected to perform emergent suprapubic catheter insertion at some time.

Ureteroneocystostomy in primary vesicoureteral reflux: critical retrospective analysis of factors affecting the postoperative urinary tract infection rates

Introduction To determine the parameters affecting the outcome of ureteroneocystostomy (UNC) procedure for vesicoureteral reflux (VUR). Materials and Methods Data of 398 patients who underwent UNC procedure from 2001 to 2012 were analyzed retrospectively. Different UNC techniques were used according to laterality of reflux and ureteral orifice configuration. Effects of several parameters on outcome were examined. Disappearance of reflux on control VCUG or absence of any kind of UTI/symptoms in patients without control VCUG was considered as clinical improvement. Results Mean age at operation was 59.2 ± 39.8 months and follow-up was 25.6 ± 23.3 months. Grade of VUR was 1-2, 3 and 4-5 in 17, 79, 302 patients, respectively. Male to female ratio was 163/235. UNC was performed bilaterally in 235 patients and intravesical approach was used in 373 patients. The frequency of voiding dysfunction, scar on preoperative DMSA, breakthrough infection and previous surgery was 28.4%, 70.7%, 49.3% and 22.4%, respectively. Twelve patients (8.9%) with postoperative contralateral reflux were excluded from the analysis. Overall clinical improvement rate for UNC was 92%. Gender, age at diagnosis and operation, laterality and grade of reflux, mode of presentation, breakthrough infections (BTI) under antibiotic prophylaxis, presence of voiding dysfunction and renal scar, and operation technique did not affect the surgical outcome. However, the clinical improvement rate was lower in patients with a history of previous endoscopic intervention (83.9% vs. 94%). Postoperative UTI rate was 27.2% and factors affecting the occurrence of postoperative UTI were previous failed endoscopic injection on univariate analysis and gender, preoperative BTI, postoperative VUR state, voiding dysfunction on multivariate analysis. Surgery related complication rate was 2% (8/398). These were all low grade complications (blood transfusion in 1, hematoma under incision ...

A new extra-abdominal channel alternative to the mitrofanoff principle: experimental and preliminary clinical experience

INTRODUCTION: The appendix is the gold-standard channel for the Mitrofanoff principle in pediatric urology, but the search for alternatives is justified considering it may not be available or preferably used for colonic stomas (Malone antegrade continence enema). The aim of this study is to report on technical feasibility of a new approach for creating catheterizable channels in a rabbit model and to present our preliminary clinical experience. MATERIAL AND METHODS: We configured a tube from two rectangular skin flaps 1x4 cm opposite each other in the middle line of the lower inferior abdomen. The channel was anastomosed to the bladder dome with embedding sutures to create a valvular mechanism. The experimental study consisted of 12 rabbits, divided in 4 groups according to the sacrifice schedule at 2, 4, 8 and 12 weeks. At 30th postoperative day, an urodynamic evaluation was performed to record continence of the stoma. A histological analysis of the specimens stained with hematoxylin-eosin, Masson trichrome and Picrosirius red was also done in group 2 (sacrifice at 4 weeks postoperatively). We used this method in 3 patients with congenital non-neurogenic bladder disease presenting with massive residual volumes without compliance deficits. RESULT: The technique proved feasible in all animals, 9 of 12 could be easily catheterized and underwent urodynamic study. No stoma leakage was observed in 7 animals at high bladder pressures (> 50 cm H20) and only 2 animals had some leakage at 40 cm H20. Urodynamics performed through the stoma showed urethral leakage at 20 cm H20, therefore demonstrating the efficacy of the valvular mechanism. Histological analysis confirmed good integration between the tube and the bladder. Mean follow-up of the clinical series (3 patients) was 7.2 months. Two patients remained continent up to 4 hours, whereas 1 patient had some leakage after 2 hours. CONCLUSION: We were able to confirm feasibility of a new extra-abdominal...

Vesicostomía cutánea: rol en la vejiga neurogénica / Cutaneous vesicostomy: in neurogenic bladder

Objetivo: En los casos de vejigas neurogénicas de alto riesgo (VNAR) se plantea la vesicostomía como una alternativa válida. El objetivo de este estudio es analizar los resultados de este procedimiento desde la creación del policlínico de mielomeningocele (MMC) en nuestro hospital. Métodos: Revisión retrospectiva de fichas clínicas e imágenes radiológicas de todos los pacientes con MMC controlados en nuestra unidad entre los años 1992-2005.Resultados: En un período de 13 años hubo 195 pacientes con MMC. De ellos 120 fueron catalogados como VNAR 69 niñas y 51 niños, sólo 20 requirieron vesicostomía. Todas fueron realizadas antes de los 4 años. Sólo 11 pacientes se han desderivado en una edad promedio de 5 años 8 meses. Cuatro pacientes están en lista de espera, 2 se cambiaron de hospital y 3 se perdieron de controles. El período de seguimiento promedio fue de 4 años. Hubo sólo 2 ostomías que se estenosaron; 1 requirió revisión quirúrgica. No hubo prolapso de las vesicostomías en esta serie. En todos los pacientes se logró estabilizar las infecciones y disminuir la hidronefrosis. No hubo pérdida de función renal en ninguno. Todos los pacientes desderivados a la fecha han requerido una ampliación vesical. Conclusiones: Podemos concluir que la vesicostomía es una buena medida que preserva la función renal, controla las infecciones urinarias a repetición y hace más fácil el manejo para los padres. Su cierre es relativamente fácil y de preferencia debe realizarse antes de la etapa escolar. Generalmente debe asociarse alguna cirugía de agrandamiento vesical.

Objective: Neurogenic bladder is a condition of difficult management. In those cases of high-risk neurogenic bladder (HRNB), vesicostomy have been rise as an alternative. The aim of this study is to evaluate the results of this practice since 1992, when the myelomeningocele (MMC) clinic was created. Methods: A retrospective case note review was carried out on all patients with diagnosis of MMC who assist our clinic between 1992-2005.Results: There were 195 patients with MMC in the 13 years period; 120 were HRNB (69 girls and 59 boys) and only 20 underwent vesicostomy. All of them were done before 4 years old. 11 were closed at a mean age of 5.8 years. Four are still in the waiting list, 2/20 moved to another hospital and 3/20had been lost from follow-up. After a mean follow-up of 4 years, there were 2 stenosis; one required surgical review. There was no prolapse in this series. All children were infection free and presented a decreased of the hydronephrosis measures. There was no lost of kidney function. The 11/11 patients who had the stoma closed required a bladder augmentation. Conclusions: Vesicostomy is a good alternative to preserve kidney function, manage urine infection and make parent supervision easier. Its closing is relatively simple and we recommend to perform it before school age. All the cases in this series required a concomitant bladder augmentation.

Rabdomiosarcoma de vejiga: Presentación de un caso / Urinary bladder rhabdomyosarcoma: A case report

Se presenta el caso de una paciente de 52 años de edad que acudió a la consulta de Ginecología por un aumento de volumen en el abdomen. Se le indicó ingreso, se estudió y se diagnosticó un tumor gigante de víscera ginecológica. Se decide tratamiento quirúrgico mediante laparatomía. Durante el acto quirúrgico se demuestra que la tumoración corresponde a la vejiga, por lo que se solicita la presencia de un urólogo. Continuamos la intervención y encontramos una tumoración grande, de base ancha, que ocupa la parte posterior y lateral izquierda de la vejiga, con áreas de necrosis de color blanquecino y consistencia algo blanda. Se cateteriza el meato ureteral derecho, el izquierdo no es visible y se realiza la exéresis del tumor. Se deja una sonda Foley No. 20 por cistostomía y uretral, se cierra la vejiga en dos planos y se revisa la cavidad abdominal. Se encontraron útero y ovarios normales; colón, intestino e hígado normales. En el estudio histológico se demostró que la tumoración es un rabdomiosarcoma pleomórfico. Se siguió su evolución y se realizaron interconsultas con el servicio de oncología para el tratamiento posterior(AU)

The case of a 52-year-old female patient that was seen at the Gynecology office due to an increase of volume in the abdomen, is reported. She was admitted, studied and diagnosed a giant tumor of gynecological viscus. It was decided to perform laparotomy. During surgery, it was observed that the tumor corresponded to the urinary bladder, so an urologist was requested. The operation continued and a big tumor of wide base was found that occupied the posterior and lateral left part of the urinary bladder, with necrosis areas of whitish color and a little soft consistency. The right ureteral meatus was catheterized, the left was not visible, and exeresis of the tumor was performed. A Foley catheter no. 20 was left by cystotomy. The urinary bladder was closed in 2 planes, and the abdominal cavity was checked. Normal uterus, ovaries, colon, intestine and liver were found. In the histological study, it was proved that the tumor was a pleomorphic rhabdomyosarcoma. Its evolution was followed and interconsultations were made with the oncology service for further treatment(AU)

Arthoscopic management of meniscal cysts

The aim of this prospective study was to evaluate the technique of arthroscopic meniscectomy and cystostomy as a method of treatment of such a meniscal disorder. Eleven patients were included in this study. The results were excellent in seven patients, good in three and fair in one patient. This technique preserves the meniscal tissue and has the advantages of antroscopic surgery

Modified open method [limited excision] for the treatment of pilonidal sinus

This study was done on 23 patients with pilonidal sinus disease [20 males and 3 females], with an age ranged between 16-35 years. Proper preoperative cleaning of the sinus track by a special fine brush had assessed much in proper delineation of the sinus track, any side tracks and the wall of the sac by the use of methylene blue dye, and this had assessed much the main objective of limiting the amount of excised soft tissues, that include all sinus track and the wall of the sac, thus shorten the time needed for proper healing, together with minimizing the incidence of recurrence. All patients had left the hospital 4 days after the operation. The discharge was markedly reduced within a week after the operation. Complete healing of the wound was established in 17 patients [74 percent] within 4-6 weeks, and in 3 patients [13 percent] within 7-8 weeks, and in the remaining 3 [13 percent] within 10-12 weeks. Recurrence had observed in one patient [4.3 percent]. Hygienic instructions, with depilation of hair from the region is considered as an important item to guard against recurrence, or formation of a new sinus
