[Surgical procedures of the urinary tract and male genital organs. Rates of surgical intervention: variability and its relationship with distance and income].

OBJECTIVE: To valorate the existence of the variability, in surgical rates on urinary tract and masculine genital organs, between the population of Health Centres (HC) adscribed to the Hospital of Ciudad Real. It so, quantify the influence of the distance (from Health Center to Hospital) or the income have in the variability of these rates. MATERIAL AND METHOD: Surgical activity of the period 1996-98. It has been analyzed for every procedure: residence, sex, age and type (coded by CIE 9th MC). The surgical rates, standardized for age and sex, (TFQ) for every HC has been compared whit the mean (t alpha/2 n-1 alpha = 0.99) of the distribution of rates by HC. The relation between the TFQ and distance or income has been analyzed by lineal regression and ANOVA test for one variable, using the Newman Keuls test to assess the difference of the rates between the HC at different distance or income. It has been considered as significative every p < 0.05. RESULTS: The population studied has a TFQ significatively different (p < 0.01). significant relationship exists between the TFQ and the distance. There were no relations between the TFQ for HC and the income. CONCLUSIONS: 42% of the variance (variability) of the distribution of TFQ for HC is due to the distance.

[Urodynamics rationale. The flow curve].

OBJECTIVE: To describe the mathematical representation of a common phenomenon: the urinary flow curve. METHODS: The statistical adjustment for minimum squares was the method employed in the study. RESULTS: A mathematical expression was obtained with a goodness of fit for each flow curve and an acceptable margin of error. CONCLUSIONS: The model which considers the flow curve as a parabola is not useful since this is an expression of a statistical phenomenon that varies from case to case. We utilized the minimum squares fit to obtain a regression curve that provides the nearest possible representation of urinary flow. Furthermore, we consider the flow curve to be the result of forces that develop in the detrusor, which produces the complex phenomenon of voiding. This study is the first step toward the development of a mathematical representation of the urinary flow mechanics.

[The dissolution of cystine lithiasis with n-acetylcysteine].

OBJECTIVE: The results of in situ dissolution of a cystine calculus is described. This approach was attempted in a female patient for whom surgery was not considered to be the best therapeutic option. METHODS: An obstructive cystine calculus was treated by in situ litholysis using N-acetylcysteine applied locally via two percutaneous nephrostomies and adjuvant oral metaphylaxis. The patient had a long clinical history of lithiasis that had also required surgery and a family history of cystinuria. RESULTS: In situ litholysis completely dissolved the cystine calculus and avoided the need for a complex surgery. The procedure and a pharmacological analysis are presented. CONCLUSIONS: In our view, this procedure is practical, carries minimal morbidity and should be considered in the management of cystine calculus.

[Fibroepithelial polyp of the ureter].

Exposition of one case of fibroepithelial polyp of the ureter in a young male patient. The interest of the case lies in the rarity of this entity. Review of all likely etiologies, clinical presentations and differential diagnosis, mainly with malignant tumours whose prognosis and treatment are entirely different. Endoscopic approach and surgical removal of the polyp and its base are the therapeutical choice for this type of neoformations.

[Primary epidermoid carcinoma of the bladder. Its diagnosis and treatment and a review of the literature].

Presentation of four patients with primary plain epidermoid carcinoma of the bladder. The patients, three men and one woman, aged 50-74 years, presented clinically with gross haematuria and irritative mictional syndrome; their background was prostatism with in-dwelling vesical catheter and repeat urinary infections. Revision of the immunohistochemical pattern and the clinico-pathological differential diagnosis, as well as the pathoetiology, biological behaviour and management of this uncommon type of tumour.

[Right hematocolpos and hematometra with left renal agenesis. A rare association. Apropos a case].

Although this anomaly is seen more frequently, the present case is unique in that the genital anomaly (imperforate vagina with the subsequent hematocolpos and hematometra) was associated with contralateral renal agenesis, whereas the cases reported in the literature have all been ipsilateral. Like most of the cases, the presenting symptom was acute urinary retention arising from extrinsic compression of the genital mass on the lower urinary tract. The embryological aspects of the genitourinary system concerning the present case are discussed, as well as some of the hypotheses that have been put forward to explain the etiology of these anomalies, although these have been developed on the basis of the associated ipsilateral anomalies observed.

[Verruciform xanthoma of the penis].

A new case of penis verruciform xanthoma in a 28 years old patient with clinical suspicion of a pre-neoplasic condition is presented. Histology and ethiopathogenesis is commented upon, with special emphasis on differential diagnosis. Healing treatment is made through simple exeresis. The extreme rarity of this bening condition's presentation and location justifies publication since it represents one sixth of the reviewed literature.

[Vesical malacoplakia].

We present a new case of vesical malacoplakia in a 55-year-old male with acute clinical cystitis accompanied by hematuria. We underline the favorable response to treatment with cholinergics and sulfonamides. We comment on the different etiopathogenic and endoscopic points of view. We review the different therapeutic concepts of this singular affection.
