[Urinary continence after radial prostatectomy. Prognostic factors and recovery time]. / Continencia urinaria tras prostatectomía radical. Factores pronósticos y tiempo de recuperación.

OBJECTIVES: To assess the urinary continence after radical prostatectomy and its evolution over time. To analyse possible prognosis factors. MATERIAL AND METHODS: We have reviewed 101 patients that have undergone radical prostatectomy. We define "continent patient" as that one who doesn't require any type of urinary protection. By means of Kaplan-Meier method, we evaluate the recovery of continence along time. We analyze potential conditional factors (age, stage, surgery technique, surgery experience,...). The statistical tools used are: chi-square, Fisher, Cox regression, T-test and Kaplan-Meier. RESULTS: Median monitoring time: 27.33 months. 80% are continent patients, 48.7% of which reach maximum continence before the 3rd, month is due and 17.5% after the 6 months (2.5% between 9-12 months). Their probability of becoming "continents" during the first 4 months es 0.4692. patients under 70 years old recover continence before those who are over 70 years old (medians: 3.51 months and 5.67 months respectively, p = 0.0211). CONCLUSIONS: The recovery of continence takes place progressively and a 17.5% of patients reach plain recovery in the 6-12 months period after surgery. The evaluation of the surgery treatment to correct incontinence should consider the possibility of "spontaneous" recovery in a 2.5% of patients in the 9-12 months period after surgery. Age affects negatively the recovery time; it is significantly less for patients under 70.

[Retroperitoneal leiomyosarcoma]. / Leiomiosarcoma retroperitoneal.

We report a case of retroperitoneal leiomyosarcoma recurrence. This entity is rare, < 0.2% of all tumours in humans and 25-30% of retroperitoneal sarcomas. The diagnosis is usually delayed in relationship with scarce clinical signs which favorite the development of great tumour volume before diagnosis. The treatment is surgical, with wide margins excision. Radiotherapy and chemotherapy are not adequates for treatment of this pathological entity.

Continencia urinaria tras prostatectomía radical. Factores pronósticos y tiempo de recuperación / Radical extracorporeal lithotripsy cause hearing loss?

OBJETIVOS: Valorar la continencia urinaria tras prostatectomía radical (P.R.) y su evolución en el tiempo. Analizar posibles factores pronósticos. MATERIAL Y MÉTODOS: Revisamos 101 pacientes sometidos a P.R. Definimos como "paciente continente" aquel que no precisa ningún tipo de protección urinaria. Mediante el método de Kaplan-Meier se evalúa la recuperación de la continencia en el tiempo. Se analizan potenciales factores condicionantes (edad, estadio, técnica quirúrgica, experiencia quirúrgica...). análisis estadístico: Kaplan-Meier, chi-cuadrado, Fisher, t-test y regresión de Cox. RESULTADOS: Mediana de seguimiento: 27,33 meses. El 80 por ciento son continentes, adquiriendo la máxima continencia un 48,7 por ciento antes de los 3 meses, y un 17,5 por ciento después de los 6 meses (2,5 por ciento entre 9-12 meses). La probabilidad de que se hagan continentes durante los primeros 4 meses es del 0,4692. los pacientes < 70 años recuperan la continencia antes que los >70 años (mediana 3,51 meses y 5,67 meses respectivamente, p = 0,0211).CONCLUSIONES: La recuperación de continencia se establece progresivamente, mejorando hasta un 17,5 por ciento de pacientes entre los 6-12 meses. La valoración de tratamiento quirúrgico para corregir la incontinencia debe considerar la posibilidad de mejoría espontánea en el 2,5 por ciento de pacientes entre los 9-12 meses. La edad influye en el tiempo de adquisición de continencia, siendo menor en < 70 años (AU)

[Signet ring-cell adenocarcinoma in colocystoplasty]. / Adenocarcinoma de células en anillo de sello en colocistoplastia.

We report a case of signet ring-cell adenocarcinoma in augmentation colocystoplasty. We review the current literature about tumours developing in augmentation bladder.

Leiomiosarcoma retroperitoneal / Retroperitoneal leiomyosarcoma

Se presenta un caso de recidiva tumoral de un leiomiosarcoma retroperitoneal. Son tumores infrecuentes, representando < 0,2 por ciento de todas las tumoraciones del organismo, y de un 25-30 por ciento de los sarcomas retroperitoneales. Suelen diagnosticarse tardíamente debido a su vaga sintomatología, alcanzando grandes volúmenes tumorales. El tratamiento es la completa escisión quirúrgica con amplios márgenes, no habiendo demostrado utilidad otras terapias como la radioterapia o la quimioterapia (AU)

Adenocarcinoma de células en anillo de sello en colocistoplastia / Signet ring-cell adenocarcinoma in augmentation colocystoplasty

Aportamos un caso de adenocarcinoma de células en anillo de sello en una colocistoplastia. Revisamos la bibliografía existente sobre tumoraciones desarrolladas en ampliaciones vesicales hasta la fecha actual (AU)

[Pure prostatic leiomyoma]. / Leiomioma prostático puro.

We present a case of pure prostatic leiomyoma, benign and rare entity, diagnosed in a patient with prostatism. We review the published papers about this disease and the different subjects about etiology, clinic, histopathology, diagnosis and treatment.

Leiomioma prostático puro / Pure prostatic leiomyoma

Se presenta un nuevo caso de leiomioma de próstata puro, tumor benigno de presentación infrecuente, diagnosticado en un varón con prostatismo. Se realiza revisión de la literatura existente y se comentan los aspectos etipatogénicos, clínicos, anatomopatológicos, diagnósticos y terapéuticos (AU)

[Acute kidney failure secondary to inguinoscrotal bladder hernia]. / Fracaso renal agudo secundario a hernia vesical inguinoescrotal.

Bladder hernia is not a rare pathological condition, with a frequency between 0.3% and 3%, reaching the 10% between patients older than 50 years. Massive bladder hernia is less frequent and very rarely ureterohydronephrosis is associated with this pathology, given that the trigone is the only portion remaining fixed after herniation. Five cases have been described in the literature reviewed affecting ureters. The present paper represents the fourth case of bilateral ureterohydronephrosis in the literature. The treatment is surgical correction of the inguinoscrotal hernia.

[Chromophobe renal carcinoma. Case report]. / Carcinoma cromófobo renal. Aportación de dos casos.

Human chromophobe renal cell carcinoma is an infrequent neoplasm, recently descripted (1985). It is very important to separate it from the renal cell carcinoma due to its better prognosis. Presentation of the clinical, radiographic and histological features of two cases of chromophobe renal cell carcinoma, diagnosed and treated in our Centre.

[Inverted papilloma of the ureter. Apropos of a case]. / Papiloma invertido de uréter. A propósito de un caso.

Presentation of one case of inverted papilloma of the renal pelvis, an uncommon entity with very few cases described in the international literature. The pathoanatomic presentation is that of a benign tumour, which would provide an option for conservative therapy through segmentary resection and termino-terminal anastomosis. Due to its low frequency, pre-operative diagnosis of this tumour is difficult, although the number of diagnosis could be increased with the use of endourologic techniques. In spite of the benign nature, it can be multifocal and relapsing. A close follow-up monitoring is recommended.

[Wunderlich's syndrome: report of 3 cases]. / Síndrome de Wunderlich: a propósito de tres casos.

Report of three cases of Wunderlich Syndrome secondary to renal adenocarcinoma, hydronephrosis and non-filar blood dyscrasia, highlighting its uncommon etiology. Brief review of the etiopathogenic, diagnostic and therapeutical aspects, pointing out the relevance of renal ultrasonography and, most specially, abdominal CAT to achieve a definitive diagnosis and to determine the attitude to follow, trying to use conservative surgery whenever possible, although our three cases were treated with nephrectomy.
