[Urologic complications of diverticulosis of the colon]

In this paper the complications of colonic diverticulosis are reported, on the basis of two clinical cases personally observed. In the first case, a 68 year-old man, the typical symptomatology with pneumaturia, cloudy urine and watery diarrhea suggested a uro-colonic fistula, therefore a fistula between sigma and bladder, caused by a perforate diverticulum, has been diagnosed by means of cystography and barium enema. In the second case, a 64 year-old woman, the irritative symptomatology, hematuria and endoscopic picture suggested a vesical neoplasia. An accurate examination with abdominal TAC and barium enema, showed a perforate diverticulum between uterus and bladder, without affecting the bladder lumen. The surgical treatment required, in both cases, a left hemicolectomy, a minimal bladder resection in the first case, and a greater one in the second case. During the discussion, the main etiopathogenetic causes of uro-colonic fistulae together with the variants in the onset symptomatology, have been stressed.

Prostatic carcinosarcoma

A unique case of carcinosarcoma of the prostate in a 66-year old man is presented. The patient underwent a total prostatectomy under the diagnosis of prostatic carcinoma. Despite adjuvant radiotherapy, the patient died about 3 months after the operation. The surgically resected primary tumor was composed of two histologically distinct elements, an adenocarcinoma and sarcoma with various mesodermal components. These elements were intimately intermingled and transitional forms were often noted. The sarcomatous portion contained areas of chondromatous differentiation. The pathogenesis of this complex neoplasm is discussed.

[Rupture of the upper urinary tract during renal colic. Two cases]

The rupture of the upper urinary tract is an uncommon event. The authors describe 2 cases during renal colic and they write, particularly, about the diagnostic and therapeutic aspects of this pathology.

[A case of adrenal neoplasm]

Pheocromocytoma is a rare adrenal tumor. Generally its size is reduced and it is one of the causes of arterial hypertension. The authors present a case of giant pheocromocytoma, without arterial hypertension, and particularly they write about the used diagnostic and therapeutic management.

[Large inguino-scrotal bladder herniation]

The authors describe a case of voluminous inguinoscrotal bladder erniation. They write about the subjet with the help of the literature and above all they show the possible dangers of a vesical underestimated injury.

[Role of the markers PAP-PSA in the diagnosis of cancer of the prostate]

The Authors report their personal experience relating to diagnostic screening for prostatic carcinoma using serum assays for specific markers of this tumour: prostatic acid phosphatase (PAP) and prostatic specific antigen (PSA). They underline the importance of high serum values of these substances, especially in tumors in an advanced state, and point out that these markers can play a role both in the diagnosis and in the follow-up of prostatic carcinoma.
