[Renal tuberculosis with pseudotumoral form: apropos of a case].

The authors report about one rare case of renal tuberculosis in a pseudo-tumoral form, which had radiologic appearances compatible with a kidney cancer invading soft tissue. The fast spontaneous evolution towards fistulization allowed confirming the diagnosis of urinary tuberculosis. The outcome with treatment was favorable. The authors recommend that needle biopsy should be made in cases of doubtful kidney tumors to provide an exact diagnosis.

[Spontaneous subcapsular hematoma of the kidney during periarteritis nodosa].

The authors report a case of spontaneous bilateral subcapsular haematoma of the kidney in a patient with polyarteritis nodosa. Although often easy to diagnose, the aetiology of these spontaneous subcapsular haematomas is sometimes difficult to establish despite ultrasonography and computed tomography. The authors emphasise the value of arteriography in these cases, which may reveal pathognomonic signs of polyarteritis nodosa. In this case, the diagnosis was established on the basis of arteriographic findings and the American College of Rheumatology criteria and not on histological criteria.

[Retrocaval ureter. Apropos of 6 cases].

The authors report six cases of retrocaval ureter discovered in quite various circumstances. A genital malformation associated to the retrocaval ureter was found in only one case. Five of our six patients were operated. Four of them underwent uncrossing of the ureter relative to the vena cava, and a patient underwent nephrectomy because her kidney was destroyed. The sixth patient was not operated because there was no impact on the excretory cavities of the kidney. This series and the review of the literature allow specifying the course of action for this pathology.

[Retrovesical hydatid cyst. Apropos of 2 cases].

A hypogastric mass compressing the bladder in an adult, in a zone endemic for hydatid disease, should raise to suspicion of a retrovesical cyst, especially as the cyst sometimes opens into the bladder resulting in haematuria and hydatiduria. Intravenous urography and ultrasonography facilitate the topographical diagnosis. Treatment is surgical: transperitoneal cystectomy and pericystic resection as extensive as possible with exploration of the abdomen looking for other sites (liver, mesentery, omentum). This treatment was successful in the two cases reported here. In conclusion, a stable cure can be obtained by adopting a well defined therapeutic approach to these rare lesions.

[The valves of the ureter. Apropos of 2 cases].

The authors report two cases of congenital ureteral valves of the upper third of the ureter complicated by renal stone in two children and diagnosed by I.V.P. The two patients underwent a resection of the pathological segment and a pelvic-ureteral anastomosis successfully. The review of the literature data regarding ureteral valves allowed to emphasize the uncommon of the bilateral form complicated by renal stone and the better preoperative diagnosis by ureteroscopy and antegrade pyelogram.

[Cancer of the urachus].

We report a case of mucin-producing adenocarcinoma of the urachus. Preoperative diagnosis was established by computerized axial tomography. An en bloc resection was performed, including the urachus with supravesical mass and bladder dome.

[Calcified necrosing cystitis].

Calcified necrotising cystitis is an urological curiosity, the authors report two cases. With subsidence of the acute process, regeneration and fibrosis take place, with contracture of the bladder and reduction of its capacity. Augmentation ileocystoplasty was performed with success in one case. The clinical and therapeutic aspects of this rare disease are discussed.

[Cervico-prostatic incision in the treatment of benign prostatic hypertrophy. Apropos of 40 cases].

The authors report on the results of 40 cases of cervico-prostatic incision for benign prostatic hypertrophy. Evaluation of the prostatic gland was based only on rectal examination. Operative technique is simple. We have treated patients with prostatic hypertropy less than 30 g. Young men with prostatic hypertrophy greater than 30 g have been treated by this technique, to preserve antegrade ejaculation. Success rate was 90% at 6 months and 85% at 18 months. Retrograde ejaculation was observed in 21% of the patients following treatment.

[Spontaneous subcapsular hematoma of the kidney].

A case of spontaneous subcapsular hematoma of the kidney is reported. CT scan findings and etiologies are examined in the light of previously published data. An etiology-specific therapeutic strategy for subcapsular hematoma of the kidney is proposed.

[Xanthogranulomatous pyelonephritis. Apropos of 42 cases].

The authors report their experience of forty-two cases of xanthogranulomatous pyelonephritis. They point out the various difficulties of preoperative identification of such diseases by the imaging modalities. They also discuss the main pathogenic hypotheses proposed in the literature.

[T1 bladder tumors. Can they be considered superficial?].

The authors report about a series of 60 cases of superficial (Ta and T1) bladder tumors and study their evolution towards infiltration according to the grade, size and number. 16% of the T1 tumors evolved towards infiltration and/or metastatic spread after a period of 42 months. In our opinion, T1 tumors can be regarded as superficial tumors. However, our therapeutic attitude is cautious because of pejorative factors of prognosis: high grade, multiple foci, and size exceeding 5 cm.

[Ectopic implantation of the ureter. Apropos of 2 cases].

We report two cases of urinary incontinence secondary to ectopic ureteral implantation with pyeloureteral duplication in a 14 and 18 year-old girls. Our observations are discussed with the review of the world publication about this data.
