We present our penile curvature treatment experience in Peyronie's disease and cogenital curvature, using a modificated plication technique of the tunica albuginea with Prolene inverted sutures covered with Vicryl ones. The first suture gives security to the plication and the second one hides the first dots avoiding the nonabsorbable sutures bother.

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.

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.
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.
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.

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.
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.
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.
We want to present a case of postraumatic hematoma in a tumoral kidney. The diagnosis of the hematoma was made by abdominal scanner but not the tumor type. It was necessary the chirurgycal review and pathological study to demonstrate an angiomyolipoma as the cause of the kidney hematoma.
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.
The endoscopical resection of the urether in the radical nephroureterectomy is an easy way to treat transitional cell carcinoma of the upper urinary tract. We want to present a complication derived from this surgical technique: the tumor implantation in the resected ureteral meatus zone.
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.
A 45 year old male patient is attended for a marked increase in the size of the left hemiscrotum totally painless. The diagnosis was haematocele, but no cause was found for the bleeding. Orchidectomy and complete exeresis of the tunica vaginalis was carried out.
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.
