[Unusual case of inverted papilloma in a fibro-epithelial polyp of the ureter].

Inverted papilloma of the upper urinary tract is a rare lesion and the differential diagnosis with transitional cell carcinoma is really hard. A case of 49 year-old male with recurrent right flank pain is reported. Excretory urogram suggested a filling defect involving the right mid ureter and bilateral retrograde pyelogram that confirmed a solitary filling defect in the right mid-ureter, while selective urinary cytology was positive for transitional cell carcinoma G1. Conservative therapy was carried out and 2 years follow-up with several excretory urograms and ultrasound studies revealed no recurrence.

[Interstitial laser therapy in benign prostatic hyperplasia].

The interstitial laser therapy is a low invasivity system for prostatic benign hyperplasia. We report our experience with Indigo 830e new system where diode laser and optical temperature sensor warrant a laser-induced interstitial thermal therapy able to continuously adjust energy delivery to the tissue.

[Bilateral renal oncocytoma. A clinical case and review of the literature].

Renal oncocytoma is an epithelial tumour of the kidney, originally considered benign neoplasm, but now it is thought have a limited but real malignant or metastatic potential. Usually monolateral, in 6% of cases it is bilateral in a synchronous or metachronous way. A case of bilateral renal oncocytoma in a 56-year-old woman, observed by chance during a follow-up carried out after breast cancer is described. The etiopathogenic and clinical-therapeutic aspects of this neoplasm are examined, and the conclusion is drawn that the most correct therapeutic approach must aim at both the protection of kidney function and complete removal of the tumour.

[Eosinophilic cystitis: an incidental diagnosis. An underdiagnosed entity].

The authors report on two cases of eosinophilic cystitis diagnosed by chance, are reported. Both patients had suffered from prostatic and vesical diseases. Since the endoscopic appearance and clinical manifestation of this disease are aspecific, the diagnosis of eosinophilic cystitis is always made on histological specimen. Even if it has been described as a rare entity, personal opinion is that the real incidence of eosinophilic cystitis is underestimated. The main features of pathogenesis and therapy are also described.

[Value and limitations of transrectal ultrasonography and computer tomography in preoperative staging of prostate carcinoma].

A careful evaluation of local tumoral extension is mandatory in patient selected for radical surgery for prostate cancer. Nevertheless, prostatic imaging, achieved with transrectal ultrasonography (TRUS) and CT scan, is often unable to stage accurately the disease. The Authors report a retrospective analysis of 43 patients treated with radical retropublic prostatectomy: their findings support the idea that both TRUS and CT scan are unable to define the extent of the tumor, reaching respectively accuracies of 38 and 46%. From these data they conclude that CT can be excluded from the preoperatory workup of prostate cancer, except in selected patients, at high risk of nodal metastasis on the basis of PSA. TRUS is the mainstay of prostate cancer diagnosis and staging because it guides transrectal biopsies, but any conclusion made exclusively on the base of its imaging seems not reliable.

[State of the art in Nd:Yag laser treatment of benign prostatic hyperplasia].

Laser energy is widely used in medical sciences nowadays. Recently it has gained importance in urology as an alternative treatment, less invasive than conventional surgical approaches, to benign prostatic hypertrophy (BPH). The Authors present a review of the literature describing the different approaches to the laser treatment of BPH: visual laser ablation of the prostate (VLAP), TULIP, contact vaporization and interstitial laser therapy. They try to show vantages and limitations of this technique respect to conventional surgery. They also present their personal experience with VLAP. They conclude that prostate laser therapy is an alternative to TURP for patients suffering for uncomplicated BPH of small to medium volumes (< 40 ml). According to literature's data and personal experience, it seems that VLAP, the easiest technique, is able to achieve the best results.

[Neoadjuvant chemotherapy in advanced-stage bladder carcinoma. A randomized prospective study comparing MVAC and MVEEC].

The Authors report the results with combination of cisplatin, methotrexate, vinblastine with adriamycin or epidoxorubicin (MVAC v MVEEC), in the neoadjuvant treatment of muscle-infiltrating bladder cancer (T2-4NO-1MO), before cystectomy. MVAC has been used in 29 patients and MVEEC in 25, who met eligibility criteria. Results from this prospective randomised trial show that MVAC and MVEEC can produce clinical and pathologic down-staging in 40-50% of cases: cCR+cPR are 15/28 (54%), pCR+pPR are 11/25 (44%). The survival duration of "pathologic" responders has been significantly longer than that of no responders (median no achieved at 200 weeks v 124 weeks for "pathologic" no responders). We conclude that neoadjuvant chemotherapy with MVAC or MVEEC select the more responsive patients, who have a longer survival.

[Small-cell carcinoma of the bladder: description of a case and review of the literature].

Small-cell carcinoma (also known as oat-cell carcinoma) is a rare tumor that previously concerns the lung; small-cell carcinoma of the bladder is extremely rare (0.5% of all bladder malignancies). The Authors report here the case of a 78th years old man. Fourteen months before our observation he was submitted to a partial cystectomy for a small-cell carcinoma of the bladder cupola. There was no evidence of extra-vesical location at that moment and the patient was not submitted to any adjuvant therapy. At the moment of our observation the disease was very advanced and the patient died in a few time. The Authors discuss about the therapy of bladder small-cell carcinoma in the few cases described by the literature and about the survival of those patients. A radical surgical treatment in association with an adjuvant chemo- or radiotherapy appears as a better way to treat these patients. On account of this case the Authors agree with this choice and conclude that only a combined treatment can allow a better survival.

Antimuscarinic activity of telenzepine on isolated human urinary bladder: no role for M1-muscarinic receptors.

1. The antimuscarinic activity of the selective M1-blocking drug, telenzepine, was investigated on the isolated human urinary bladder, contracted with exogenous muscarinic agonists and with field stimulation. 2. Telenzepine (3 x 10(-8)-10(-5) M) concentration-dependently shifted to the right the dose-response curves of bethanechol, acetylcholine and McN-A343, and partially depressed the electrically-evoked twitch responses. 3. pA2 values of telenzepine against bethanechol and McN-A343 were very close. 4. McN-A343 did not modify twitch responses elicited by field stimulation up to 10(-5) M. 5. The lack of muscarinic M1 receptors in human detrusor muscle is confirmed.

[Laparoscopic treatment of varicocele].

Varicocele is frequently a contributing factor in male infertility. We performed laparoscopic treatment of varicocele in 6 patients. This procedure can be carried out through three ports and allows not only ligation and excision of the dilated testicular veins, but those veins branching through the back of the inguinal canal lower down. It is a quick operative procedure and we completed it within 30 minutes. All the patients have gone home on the 2 days and, to date, there have been no complications. During a follow-up period of 3-6 months it was possible to observe the disappearance of varicocele. It is possible to conclude that the laparoscopic procedure is simple and effective as more traditional methods.

[A case of rupture of the testis].

A case of traumatic rupture of the testis is presented in which the conservative surgery was successful. The results of the ultrasonographic evaluation and of the scanning with Tc 99, executed long after the operation, are presented. The importance of an early explorative operation in all cases of post traumatic scrotal swelling is stressed. On account of the youth of most patients, the importance of a conservative surgical approach is emphasized.

[Renal oncocytoma. Ultrasonographic study of 4 cases].

The authors report four cases of renal oncocytoma investigated by echography and proved by histology after surgery. Describing the clinical cases, after a brief review of the literature, the radiologic findings are analysed with particular regard to the sonographic signs that can preoperatively differentiate oncocytomas from carcinomas. The authors conclude that the only sonographic distinguishing feature is a quite characteristic central hyperechoic streak corresponding to the fibrous scar, frequently found in this benign tumor.

[Urachal cyst. A case report and review of the literature].

The pathology of urachal disease is rarely seen. This article refers to a case of urachal cyst in a twenty-five-year-old male. In order to discuss the pathogenic, clinical and therapeutic aspects of this rare pathology, it is necessary to carry out a complete revision of the literature. Diagnosis is helped by ultrasound and CT scan of the lower abdomen, while fistulography is necessary when there is cutaneous drainage. The treatment consists of surgical approach which includes complete en-bloc excision of the cyst together with possible urachal residue. Such treatment is indispensable in order to avoid acute infection and/or malignant degeneration, frequent complications which are very serious.
