Peripheral afferent nerve stimulation for treatment of lower urinary tract irritative symptoms.

OBJECTIVES: To assess the efficacy of posterior tibial nerve stimulation for treatment of lower urinary tract irritative symptoms (urgency, frequency, urge incontinence and pelvic pain). PATIENTS AND METHODS: 51 female patients with a mean age of 55 years were enrolled in the study. The patients presented with the following symptoms: Frequency/urgency 26 patients (50.98%), urge incontinence 22 (43.13%) and interstitial cystitis 3 patients (5.88%). The technique consists in administering low voltage electric stimulation via a 3-5cm needle placed above the tibial malleolus. Patients received weekly stimulations of 30 minutes for a 10-week period. Quality of life questionnaires and voiding diaries before and after treatment were completed. Moreover, the results were evaluated by patients. The variables analysed include: daytime and nighttime voiding frequency, daytime and nighttime voiding volume, daytime and nighttime leakage episodes and hypogastric pain. RESULTS: A statistically significant improvement was seen in all variables, especially remarkable in relation to frequency/urgency, impact on women quality of life and hypogastric pain, being less marked in relation to leakage episodes and voiding volume. CONCLUSIONS: Afferent nerve stimulation offers an alternative treatment for managing lower urinary tract irritative symptoms. However, it would be advisable to confirm the results obtained by means of long-term randomized, follow-up studies.

[Bladder carcinosarcoma. A clinical case].

Presentation of a new case of vesical carcinosarcoma in a 49 year-old male patient. The tumour's pathoanatomical study showed an epithelial pattern of transitional and squamous cells and a sarcomatous pattern composed of rabdomiosarcoma, osteochondrosarcoma and pleomorphous indifferentiated sarcoma with giant multinuclear cells. Histogenesis, signs and symptoms, and treatment, as well as the need of performing an immunohistochemical study for its diagnosis are discussed.

[Giant müllerian cyst. An infrequent cause of palpable hypogastric mass].

Due to its remarkable rarity, large volume and good post-operative evolution, the authors present one case of a cyst from Müller's duct debris, 18 x 16 cm in size, in a 22-year old male who presented with tangible mass in the hypogastrium and occasional nycturia. The size conditions the clinical symptomatology, although the are times such as this, when they can acquire a considerable volume and grow with practically no symptoms. Clinical history and diagnostic methodology are explained, pointing out the most relevant clinical criteria for proper differentiation from other entities, the complexity of differential diagnosis and the therapeutical procedure used.

[Ureteral injuries following translumbar aortography].

In the already scarce traumatic ureter pathology, beyond the scope of Gynaecology, we present a case, also iatrogenic, which although it is described as a possible complication in the performing of a translumbar aortography, is of unquestionable interest by virtue of its origin and subsequent evolution.

[Unstable detrusor: usefulness of biofeedback].

Presentation of results of treatment using Biofeedback in two conditions which quite frequently associate vesical instability and incontinence: 65 cases of enuresis and 39 of urinary stress incontinence in females. The method was effective and achieved disappearance of detrusor instability in 78.2% of enuretic cases and 58.9% of urinary stress female incontinence. Outcome for incontinence was less favourable since disappearance was only achieved in 70.5% of enuretics and 20.5% cases of female incontinence. A brief description of the method and instrumentation used is done, which can be easily conveyed to any electromiographic device with real time output. The paper substantiates the authors' views relative to the likely pathogeny of the instability in both processes and the mechanism of action of Biofeedback techniques.

[Urodynamics in kidney transplantation].

OBJECTIVES: The importance of establishing a protocol for the urological evaluation of patients awaiting renal transplantation is due to the fact that 30% of these adult patients and up to 70% of these children develop renal failure due to a urological condition. The present study analyzes the importance of urodynamic evaluation in these patients. METHODS: 650 patients awaiting renal transplantation were evaluated by patient history, physical examination, US, Cystouretyhrography, and flowmetry. Thereafter 201 patients with the following conditions were selected for urodynamic assessment: vesicoureteral reflux, changes in bladder morphology (diverticulum, trabeculation), inadequate infundibulization of the bladder neck, diabetes, neurogenic bladder, obstructive pathology and bladders with a small volume capacity. The urodynamic study consisted of instantaneous voiding, cystomanometry and urethral pressure profile. RESULTS: Of these 201 patients, 45 had vesical hyperreflexia, 45 bladder disuse, 95 had a normal bladder, 12 had a hypoactive bladder and 2 had detrusor instability. CONCLUSION: The urodynamic study, apart from flowmetry, is basically indicated in patients awaiting renal transplantation who have a neurogenic bladder and/or suspected as having lower urinary tract obstruction.

[Biofeedback as a therapeutic alternative in uncoordinated miction].

The Hinman Syndrome is known as an involuntary unsconscions contraction of the periurethral sphincter during micturition once neurologic disease and anatpmical obstruction are rejected. We report a case of a 23 years old man who was diagnosed of suffering from this syndrome. After the proper studies and left nephroureterectomy for ureterohydronephrosis secondary to long term massive vesicoureteral reflux, we proceeded to treat him with biofeedback and autocatheterisms. Six months after, the patient was asymptomatic with normal micturitions without residue.
