[Stage pT0 bladder tumors after radical cystectomy: a review of our series].

OBJECTIVES: To evaluate the data of progression and survival in 43 patients who underwent cystectomy with stage pT0 according to classification TNM-2002. MATERIALS AND METHODS: between 1988 and 2003 in our center had realized 420 cystectomies, 43 patients (10.2%) had not tumor in the cystectomy specimen. RESULTS: In these 43 cases the initial clinical stage (in the transuretral resection of bladder) was T1 in 10 cases (23,3 %), T2 in 31 cases (72%) and T3 in 2 cases. As far as the degree 24 patients presented G2 (55.8%) and 19 (44.2%) were G3. Median time from the transuretral resection to the cistectomy was of 44 days at a median follow-up of 89.3 months. Progression-free survival in the 43 patients was of 180,6 months, but during the follow-up it appeared progression in 7 patients, with disease free survival at 36 months (3-126), since the date of the cistectomia. During the follow up, 5 patients died. When we analyzed the cancer-specific survival according to tumor stage, for the T2 with an average cancer-specific survival is of 180 months, decreasing to 35 months considerably for T3. Similar it happens with the degree of differentiation, significantly diminishing as it advances the degree, with an average of cancer-specific survival for the G3 at 122.6 months. In the same way it happens with pathological positive lymph nodes in the radical cistectomy, with a cancer-specific survival of 188 months when it is N0 and of 54 months if the adenopathy was positive (N+). CONCLUSION: In our experiencie urothelial carcinoma pT0 present a prolonged free period of disease (medium of 180 months). The associated factors of risk to a smaller free period of disease are high degree of differentiation (G3, 116 months), the infiltration of deep layers in the transuretral resection (T3, 32 months) and the ganglionary affectation (pN+ 45 months).

[Treatment of hemorrhagic cystitis secondary to cyclophosphamide. Literature review with regard to a case].

There are extreme situations in the clinical treatment of intractable hematuria (fortunately not a common disease nowadays), in which even benign process may represent a serious risk to the life of the patient and where certain aggressive procedures like cystectomy have to be considered. Our objective in this paper is to review the different existing therapeutic alternatives for the treatment of an intense type of hematuria which does not yield to continuous saline serum irrigation. This study is partly based on a recent real clinical case in which, after the administration of cyclophosphamide to a young patient with recurrent and intense hematuria, the excretion was controlled through intravesical alum irrigation of thus avoiding cystectomy, a very aggressive surgical procedure with many after-effects.

[Primitive neuroectodermal tumor. Ewing's sarcoma].

Primitive neuroectodermal tumor is an extraordinarily rare primary tumor in the kidney and can be mistaken for a variety of other round cell tumors. It is important to recognize each of these entities, because each carries unique therapeutic and prognostic implications. However, accurate diagnosis of these tumors is hindered by their significant morphologic overlap and complicated by their rarity. These neplasm are highly aggressive that tend to recurence and to metastatize. Standard therapy combining surgery, chemotherapy, radiation and genetic therapy. We report a case of primitive neuroectodermal tumor of the kidney in a 50 year old female patient.

[Renal teratoma, case report and review of the literature].

We report a case of intrarenal teratoma in a 39-year-old female patient. The clinical course after three years of follow-up has been satisfactory, finding the patient totally asymptomatic. Extragonadal teratoma occurs predominantly along the median line of the body. Intrarenal teratoma is extremely rare; however, it should be distinguished from other cystic lesions.

[Pure primary prostate transitional cell carcinoma. A review of our series].

Primary prostate transitional cell carcinoma is a very uncommon tumor, that represents about 1% of all prostate tumours. In our institution, only six patients have been diagnosed with pure transitional cell prostate carcinoma until 2002. Bladder origin of the neplasic was ruled out in all cases. We report a study about the progression and survival of prostate transitional cell carcinoma. These prostatic tumours carry a poor prognostic (median survival is 4.6 months) with a strong tendency to metastatic spread. Therefore, we suggest a radical prostatectomy (without cystectomy) when it rules out bladder origin tumour.

[Foreign body simulating kidney tumour].

A six cm kidney tumour is found in a prostate control ultrasonography, in a 70 aged men. A chirurgical remove is indicated the tumour presented a very few separation of the kidney. The kidney was only compressed by the mass which contained a chirurgical gauze inside it from a previous surgery 35 years before.

[Pseudotumor renal after partial nephrectomy with the use of surgical gelatin sponge].

After renal parenchymal sparing surgery, with the use of surgical gelatin sponge, residual defects may persist on imaging studies at the sites of resection. These "pseudotumors" may lead to confusion as to whether a lesion was removed or has recurred. These lesions usually resolve within a year. We report a case of pseudotumor renal parenchymal sparing surgery in a 69 year old man, with resolution of the lesion 8 months after surgery.

[Priapism as an initial presentation of chronic myeloid leukaemia].

We report the case of a 29 years old patient who presented, in the last three moths, four episodes of priapism without any other symptoms and any previous traumatism. An hemogram reveled that the repeted episodes of priapism were caused by a chronic myeloid leukaemia.

[Skin metastasis of urothelial bladder tumor].

We want to present a case of tranticional cell bladder carcinoma, where the first sign of disease progression was the appearance of a skin metastase. An unusual manifestation in a patient without another metastatic lesions.

[Penile curvature secondary to cavernous body abscess].

A case of unilateral cavernosal body abscess appears after fifteen days of 40 degrees C fever, without urological symptoms. The diagnosis started from a big scrotum aedema, related of a local septic focus in the left cavernosal body. ECO and TAC confirmed the diagnosis, and a surgical treatment was required. After a successful evolution, the patient presents a left penile incurvation with pain and difficulties during the sexual relations, but he did not accept any treatment.

[Intravesical foreign bodies. Review of the literature].

We want to make a literature review about the bladder foreign bodies. This clinical situation is not an usual emergency, but there are a lot of references in urological articles about it. In this article review we want to make a compilation about the symtoms, the different origins of the foreign bodies, and ways of diagnosis and treatment of this pathology. We also want to add our personal experience in a recent case.

[Retroperitoneal fibrosis caused by pancreatitis in an HIV+ patient].

Retroperitoneal fibrosis is a rare inflammatory disease, in which the fibrosis plate leads to the compression of the affected structures. There are several causes of retroperitoneal fibrosis like specific and unspecific inflammatory diseases. In the specific group of retroperitoneal fibrosis we find the one due to pancreatitis. We do present a rare case of retroperitoneal fibrosis caused by a pancreatitis in a HIV+ patient.

[Pelvic recurrence of urothelial tumor, after radical cysto-prostatectomy with orthotopic neo-bladder].

We present a case of an urothelial tumor pelvic recurrence, five months after radical cystoprostatectomy. No fat infiltration was demonstrated in the pathological study of the transurethral resection pieces. The treatment was a radical cystoprostatectomy with an ileal ortothopic Hautmann type neo-bladder. The pathological study of the surgical piece demonstrated fat infiltration in some points but urethra and lymphatic nodes free.

[Kidney transplantation. Technique and complications].

We want to make in this article, a deep review of our experience in kidney transplantation since the moment we started the technique in 1986 to the end of the year 2000. We also want to make a compilation of the most important points of the surgical technique, patients selection criteria, and the most common and uncommon complications that can appear in kidney transplantation, analizing our results all along this time.
