Resume Les auteurs rapportent deux cas de kyste hydatique developpe dans le cul-de-sac de Douglas et rompu dans la vessie. La clinique etait dominee par les signes urinaires, l'hydaturie etait evocatrice de l'hydatidose. L'echographie a permis de localiser la masse retrovesicale, de definir ses caracteres et d'eliminer d'autres localisations abdominales et retroperitoneales. Le traitement a consiste en une perikystectomie par voie sous-peritoneale dans un cas et l'instillation intravesicale d'eau oxygenee dans un autre. L'evolution etait favorable dans les deux cas.

The authors report two cases of renal multilocular cyst and review the cases reported in the literature, revealing the original features of this benign tumour which has an equal incidence in children and adults with a controversial acquired or malformative aetiopathogenesis, precise histological features, but a difficult preoperative and intraoperative diagnosis despite modern imaging techniques. In the great majority of cases, treatment consists in nephrectomy.

Resume Les auteurs rapportent deux cas de testicules cryptorchides intra-abdominaux chez l'adulte. Il discutent les problemes diagnostiques et therapeutiques de cette affection rare, en insistant sur la place de la cœlioscopie, technique simple qui permet, outre la certitude diagnostique, de realiser chez l'adulte une orchidectomie etant donne le risque de degenerescence eleve de ces testicules.

In this study, the case has been reported of a left renocolic fistula that was detected in a patient with hepatitis C and cirrhotic complications who was hospitalized for urogenital tuberculosis. It was decided to perform left nephrectomy and digestive suture, but surgery was delayed due to hemostatic abnormalities and massive cytolysis, and the patient died before surgical treatment, three days after the discovery of the fistula. The findings in the literature have been reviewed, and the common occurrence of this type of fistula has been underlined. They are the most frequently encountered type with of entero-urinary fistula, and account for 60% of documented cases. Their etiological and clinical characteristics of have been described in detail. In general, treatment consists of performing a nephrectomy and digestive suture.

We describe the case of a 32 year old man who developed such a stenosis after surgery for traumatic rupture of the corpus cavernosum. The aetiology of this rare complication is also given. The stenosis was well outlined by cystography and responded successfully to conservative treatment.

A case of myxoid paratesticular liposarcoma in a 68-year old patient is reported. The evolution was normal during the follow-up period (22 months). Scrotal liposarcoma is a rare tumour: less than 100 cases were reported in literature. The diagnosis is difficult, clinical and radiological signs are the same as those of any intrascrotal tumour. Orchidectomy is the usual treatment, prognosis depends on the histological features, it is usually better than that of other paratesticular sarcomas. It did not need any additional treatment.

The authors reported two cases of impalpable testis in young mens. Laparoscopy is useful in both the diagnosis and the management of impalpable testes. Intraabdominal testicles can be removed laparoscopically if atrophic or can be partly devascularized by spermatic vessel clipping if apparently normal. A second-stage vasal-based orchidopexy can then be performed once adequate testicular reperfusion via the the defferential pedicle is believed to have occurred.

Spontaneous retroperitoneal hemorrhage is an uncommon affection, the diagnosis was recognized by sonography and CT scan, but the etiology remains unknown and exploration for diagnosis may become necessary. In the absence of an apparent etiology, patients with spontaneous renal bleeding should undergo radical nephrectomy, because of the extremely high incidence of small undetectable occult tumors. Three further cases were reported by the authors, who made a review of the literature.

The authors report two cases of renal multilocular cyst and review the cases reported in the literature, revealing the original features of this benign tumour which has an equal incidence in children and adults with a controversial acquired or malformative aetiopathogenesis, precise histological features, but a difficult preoperative and intraoperative diagnosis despite modern imaging techniques. In the great majority of cases, treatment consists in nephrectomy.

The present study reported two cases of hydatid cysts localized in Douglas space and that broke in the bladder. The clinical course was characterized by urinary symptoms and by presence the cysts in urine. Abdominopelvic ultrasonography is essential for diagnosis and identification of other sites. When diagnosis is unclear, then CT scan plays a role. Therapy included cystectomy and pericystic resection in one case and intravescical injection of H2O2 in the second case. The course was favorable in both cases.

Prostatic carcinoma metastasizing to the testis is an extremely rare occurrence. In this study, two new cases have been reported of unilateral testicular metastases from an adenocarcinoma of the prostate. Unlike primary tumors of the testis, this type of tumor develops later in life (between 50 and 60 years of age), and is in most instances unilateral. It is generally discovered accidentally during orchiectomy or autopsy. It is not always easy to establish a morphological diagnosis, as the macroscopic appearance of the tumor may be normal. However, microscopic investigation reveals the presence of neoplasms of the testis.

In the light of two cases of fracture of the corpora cavernosa associated with rupture of the urethra and a review of the recent literature, the authors consider that early surgical treatment is useful and the only way of ensuring rapid recovery without sequelae.

The authors report one case of indifferentiated sarcoma of the prostate revealed by phlebitis of the right inferior limb and lung's metastases in a man 41 years old. The tumor progress rapidly and infiltrate the bladder and the posterior urethra. The patient died five months later. They review the literature and study the clinical histological, therapeutic and evolutive aspects of this unusual tumor.

The authors report an usually uncommon case of psoas abscess after cystostomy for an acute urinary retention. Ultrasound and CT-Scan investigations suggested the diagnosis with confirmed by CT guided percutaneous drainage. On the basis of this observation, we discuss the mechanism and therapeutic aspects of this complication.

The development of cancer on the ileal graft after augmentation ileocystoplasty benign bladder disease is a little known complication. The authors report a case of squamous cell carcinoma in the ileal bladder occurring 31 years after augmentation ileocystoplasty for tuberculous bladder, in a 60-year-old patient. The ileal bladder was resected and a new augmentation ileocystoplasty was performed. The postoperative course was uneventful. Histological examination of the operative specimen showed infiltration of all of the intestinal wall. The patient died one year after, in a context of peritoneal carcinomatosis.

In order to clarify the place of transrectal prostatic ultrasound examination (TRPS) in the diagnosis of prostatic cancer at early stage, 666 patients have been screened in 1 year. Of these, 602 had a normal, firm, or hyperplastic but nonnodular prostate (T0) by digital rectal examination (DRE); 41 had a T1-T2 prostate; and 23 had a T3-T4 prostate. Among those with T0 prostates, 162 had a hypoechoic peripheral area, which was biopsied: 11 lesions were infiltrating carcinomas. The ability to detect a T0 cancer with TRPS alone is assessed at 1.8% (11/602). The positive predictive value of a hypoechoic image of the prostate is assessed at 7% (11/162), which is much lower than the figures reported in the literature. TRPS can be considered an acceptable means of detecting T0 tumors of the prostate with a yield comparable to that of DRE in the T1-T4 tumors. The low performance (1.8%) of TRPS in detecting cancer at early stage rules out massive screening program of the male population over 50 years old. However,...

Hydatid disease in endemic countries is common but an isolated retroperitoneal localisation is rare. After a review of the aetiopathogenesis and clinical aspects, the authors express the opinion that safe, rapid and reliable technique of echotomography is the key investigation in obtaining a positive diagnosis. In terms of its course, the histopathological appearances are those of a locally malignant tumour which as a preferential and severe effect on renal function. Surgery is the only valid method for eradication of the parasite and freeing the urinary tract.
