[Second resection in patients with Ta-T1 bladder tumors].

OBJECTIVES: To study the incidence of "residual/recurrence" tumor after a second bladder resection (2nd TUR). METHODS: 40 patients with new or recurrent superficial bladder tumor underwent repeat transurethral resection within 3 months after the initial resection. 37 patients were staged as Ta-T1. We study the incidence of tumor after the 2nd TUR both macroscopically detected or included in the bladder scar. We also study the influence of possible factors as the time between both resections, stage, grade, number of tumor size, localization in the bladder, primary or recurrent tumor and tumor pattern. RESULTS: After the 2nd TUR we found tumor in 14 of 37 (37.8%) Ta-T1 bladder tumors. Among the 14 tumors, 10 (71.5%) were macroscopically visible tumors and 4 cases the tumor were found after resection of the bladder scar of the first resection. We did not find relation between the presence of tumor in the 2nd TUR and any of the variables. CONCLUSIONS: After a TUR of superficial bladder tumor the complete removal of tumor is not always achieved. The early 3 months cystoscopy may not find residual tumor. Although we have found tumor in 37.8% in the 2a TUR we can not recommend routine 2nd TUR in superficial bladder cancer.

[Congenital bladder diverticulum and Ehlers-Danlos syndrome: an unusual association].

The existence of a vesical diverticulum in the context of a congenital connective tissue disorder such as Ehlers-Danlos syndrome led us to consider the possibility of a relationship. Four types of diverticula can be found in the literature: congenital, acquired, iatrogenic and syndrome-associated. Within the later, Ehlers-Danlos syndromes type IV and IX, even type V, are associated to the existence of vesical diverticula. The potential spontaneous rupture of the diverticulum is a typical feature, as well as post-surgery relapse. The attitude towards such diverticula should be one of watchful waiting, and simple, plasty-free diverticulectomy on the bladder's neck is indicated when performing a surgical procedure.

[Testicular tumors: our experience].

OBJECTIVE: To report our series of testicular tumors diagnosed from June 1990 to June 1998. The diagnostic protocol, treatment and follow-up are described and data on patient survival over the 8-year period are presented. METHODS: Our series comprised 21 testicular tumors; 19 germ cell and two non-germ cell tumors. There were 5 seminoma, three pure embryonary carcinoma, two mature cystic teratoma, 9 mixed germ cell tumor and two lymphoma. Treatment was by orchidectomy plus radiotherapy, chemotherapy and some cases were closely followed. RESULTS: All 5 patients with seminoma are currently tumor-free, for a mean survival of 38.6 months. Of the 14 non-seminomatous tumors, there were two deaths; the remaining patients are in complete remission, for a mean survival of 37.5 months. The overall survival rate was more than 95% at a mean follow-up of 48 months. CONCLUSIONS: Testicular tumor is one of the most common tumors in young male patients; germ cell tumors are the most frequent type. The different therapeutic regimens currently available have achieved a 5-year survival rate of more than 95%.

[Melanoma of the female urethra: a very infrequent tumor].

Case report of a melanoma of the urethra in a 75-year old female patient. A few months after diagnosis the patient died of multiple lung metastasis. This is a review of the clinical and diagnostic aspects of the neoplasia highlighting the therapeutical options that albeit debatable seem to be quite clear as to the master lines to follow.

[C.F.C.-type ureterosigmoidostomy. Results].

This paper presents the results obtained with a C.F.C. type ureterosygmoidostomy technique described by us. A total of 25 patients aged between 52 and 74 years (mean age, 65 years), 23 (23/25) male and 2 (2/25) female were evaluated. 24 of the total 25 patients had infiltrant neoplasia of the bladder (pT2: 8; pT3a: 12; pT3b: 4) which was graded as moderately differentiated (G2: 10) or undifferentiated (G3: 14). The remaining patient, a female, had tuberculous microbladder. Male patients underwent radical cystoprostatectomy (23/25); while in two females traditional cystectomy was performed (2/25). Patients with neoplasia of the bladder (24/25) were performed bilateral lymphadenectomy prior to radical surgery. All 25 patients were performed C.F.C. type ureterosygmoidostomy (Actas Urol Esp 20: 324, 1996). Follow-up of patients was carried out over a mean period of 27 months (July 1994-October 1997). The complications reported were 4 cases of ureterointestinal stricture and one stercoral fistula. The strictures were resolved with endoscopic techniques and the fistula through discharge colostomy. Death (6/25) occurred as a result of the tumour progression, and in no case was related to the surgical technique. All patients showed daytime continence (100%), and 22/25 were also continent during the nighttime (88%): there were occasional leaks in 5/25 (20%). No metabolic disorders were seen in any of the patients. (All patients were given drug therapy to prevent metabolic acidosis).

[Histologic-ultrasonographic correlation of gland asymmetry and "pseudoruptures" of the prostatic capsule].

An histo-ultrasound correlation was carried out between the information obtained with pre-operative transrectal ultrasound and that obtained with the histopathological study of 29 prostate specimens from patients with mean age 63 years (range, 52 to 71 years), who underwent radical cystoprostatectomy for infiltrant neoplasia of the bladder (22/29) and radical prostatectomy for prostate cancer (7/29). The (extrinsic and intrinsic) ultrasound parameters were analyzed focusing in the study of the prostatic capsule or "pseudocapsule". With this comparative, echographic and histological study the concept of capsular "pseudorupture" that results from the presence of (arterial and/or venous) vessels, nerves and fibromuscular folds at the periprostatic fat tissue is introduced. The interruption of the capsular echogram was seen as an indication of tumoral involvement of the capsule, and extracapsular spread. Our results allow us to suggest that this assertion should be reconsidered since these capsular "interruptions", "irregularities" or "pseudoruptures" are present in the normal prostate. Similarly, glandular asymmetry in relation with an heterogenous growth in one lobe in defined to differentiate it from that seen in neoplastic processes.

[Bladder hemangioma: a clinical case].

Contribution of a new case of vesical haemangioma in a 65-year old male. This is a benign and very rare tumour with not even 90 cases described in the urology literature to date. Haematuria was reported in all cases. This paper presents a review of the literature and a discussion of clinical and pathological features as well as diagnostic methods and recent changes in management approach.

[Glandular cystic cystitis].

Cystic-glandular cystitis is considered as part of the urothelial pre-neoplastic proliferative abnormalities. This group includes atypical hyperplasia. Von Brunn's nidus, and cystitis cystica. They are a consequence of the changes experienced at the urothelium level in response to inflammation, irritation or carcinogens. Diagnosis is mainly based in the pathoanatomical study of the biopsy obtained following endoscopic resection. The signs and symptoms it presents are varied and show a clear relationship to distribution and extension of cysts. Treatment is based in the removal of irritative factors. Cystectomy with urinary by-pass may be necessary if required by clinical evolution.

[Primary nontransitional neoplasms of the bladder].

Revision of all primitive tumours of the bladder diagnosed in our Service between July 1990 and July 1998. Among a total of 703 neoplasms of the bladder only 14 were non-transitional primitive tumours, accounting for just 1.98%. Eleven were malignant neoplasms with a diagnosis of epidermoid carcinoma in nine cases, one adenocarcinoma and one bladder adenocarcinoma. The other three were benign tumours: one haemangioma and two leiomyomas. From a clinical perspective, the predominant symptom was haematuria, followed by irritative symptoms. The two leiomyomas were accidental findings during a gynaecological examination (ultrasound) and a diagnostic examination for a nephritic colic (urography). The diagnostic means used and the extension studies were the same as used for transitional neoplasms. In general, treatment of benign neoplasms was partial cystectomy or transurethral resection while it was radical surgery for the malignant tumours when the existing criteria were an indication for that type of surgery (cystoprostatectomy with bypass), since there are no definite criteria with regards to therapy due to the low incidence of these tumours. Only three of the 11 patients with malignant neoplasms are still alive. All the others died within one year of diagnosis, an evidence of the aggressiveness of these tumours. These cases were considered primitive bladder tumours once it was concluded that there was no relation with any previous or simultaneous transitional neoplasms and that there had been no primitive tumour in a different organ.

[Bladder carcinosarcoma: case report with immunohistologic study].

We present a new case of carcinosarcoma of the bladder. This tumor is generally considered to be a rare one, has an uncertain aetiology and very poor prognosis, composed by mesenchymal and epithelial elements. It is an aggressive tumor with a short clinical course. At present radical cystectomy is the treatment of choice.
