Eosinophilic cystitis induced by bacillus Calmette-Guerin (BCG) intravesical instillation.

Eosinophilic cystitis is a rare and uncommon inflammatory bladder disease, in which the pathophysiology is unclear; only a few cases of such disease induced by intravesical instillations have been described. We report a case of eosinophilic cystitis after intravesical bacillus Calmette-Guerin (BCG) instillation for nonmuscle-invasive transitional cell carcinoma of the bladder. To our knowledge, this report is the first case of eosinophilic cystitis induced by intravesical BCG therapy.

[Hydatid cyst of the spermatic cord].

The authors report the third published case of hydatid disease of the spermatic cord and describe its unusual presentation in the form of hydrocele. Hydatid disease is endemic to some countries, where it constitutes a real public health problem. It can affect all organs of the body.

[Ureterocalicostomy: indications and results based on a series of 16 patients].

Formerly considered to be a salvage or last resort technique before nephrectomy, ureterocalicostomy can be indicated in certain well defined situations, when strictly dependent drainage of urine is essential. Due to its particular indications, this procedure is rarely performed and operators have limited experience. The authors report 17 cases of ureterocalicostomy performed in 16 patients: 8 cases obtained an excellent long-term result with absence of clinical signs, urinary tract infection and proximal dilatation of the neo-junction.

[Skin metastasis from invasive bladder tumour].

Metastatic spread of advanced transitional cell bladder carcinoma rarely involves the skin. However, the presence of a skin metastasis indicates at least microscopic dissemination of cancer cells to the liver or lung, corresponding to a poor prognosis. The authors report a new case of single skin metastasis during the course of a poorly differentiated stage pT3a N0 M0 transitional cell bladder carcinoma.

[An experience of individual and early diagnosis of prostate cancer in a Tunisian centre].

Introduction: The introduction of prostate specific antigen (PSA) and progress in transrectal ultrasound and ultrasound-guided prostatic biopsies have allowed considerable progress in the diagnosis of prostate cancer. However prostate cancer is still usually diagnosed at an advanced stage in Tunisia.

Methods: We prospectively evaluated the prevalence of localized prostate cancer in the population of a Tunisian centre during a screening programme.
