[Trigonocervicoprostatotomy. Results in 205 cases].

OBJECTIVE: To analyze the results of transurethral incision of the prostate in 205 patients with prostatic obstruction. METHODS: 205 patients comprised the study. The clinical records and surgical reports were reviewed for patient age, pre and postoperative symptoms, physical examination (principally digital rectal examination), ultrasound findings (prostate weight), endoscopy, type of surgery (type of incision), operating time, hospital stay and complications. RESULTS: 37.07% were aged 60-69 years, 59.51% were grade I according to the DRE and ultrasound findings, and prostatic weight. Bilateral incision was performed in 65.36%. The operating time was 15 minutes in 79.02% of the cases and the length of stay was 3 days in 89.75% of the cases. Postoperative hematuria was the most common complication. CONCLUSIONS: Endoscopic transurethral incision of the prostate is an alternative minimal invasive surgery in the treatment of early onset benign hyperplasia of the prostate with small prostates and short urethras.

[Well differentiated mucus-producing adenocarcinoma of the right renal pelvis. Presentation of a case].

OBJECTIVE: To present a rare case of well-differentiated mucus-producing adenocarcinoma of the renal pelvis. METHODS: Patient history, the results of the complementary tests after surgery, treatment and anatomopathological findings are presented. RESULTS/CONCLUSIONS: Well-differentiated mucus-producing adenocarcinoma of the renal pelvis is rare and is often associated with lithiasis, a long history of obstruction and inflammation. Nests of tumor cells surrounded by abundant mucus is a characteristic histological finding in this tumor type.

[Renal neurilemmoma. Apropos of a case].

OBJECTIVE: To report a case of renal parenchymal neurilemoma and review the literature. METHODS/RESULTS: A 44-year-old male patient presented with total hematuria. Patient evaluation by IVP, renal US and CT revealed a right renal mass. Radical nephrectomy was decided. The anatomopathòlogical analysis showed a renal parenchymal neurilemoma. CONCLUSIONS: Renal parenchymal neurilemoma is a rare benign tumor. The diagnosis is based on the clinical symptoms and the IVP, renal US and CT findings and confirmed by the anatomopathological findings. Surgical resection achieves cure and there is usually no recurrence.

[Priapism. Our experience].

OBJECTIVE: We report our experience in the diagnosis, medical management and surgical treatment of priapism. METHODS/RESULTS: The clinical records of 67 patients that had been treated for priapism at our hospital from 1978-1994 were analyzed for age, race, occupation, marital status, symptoms, treatment, complications and time to remission of symptoms following treatment. Sixty-four patients were treated surgically and 3 patients were successfully treated medically. We performed 52 cavernospongiosal shunts, 14 sapheno-cavernous shunts and in 10 patients corpora cavernosa puncture was performed. The complications were sepsis, thrombosis, hematoma, phlebitis and urethral fistula. The complication rate was low for the cavernospongiosal shunt and corpora cavernosa puncture with phenylephrine. CONCLUSIONS: The highest incidence was observed in patients aged 15-40 years, with a prevalence in the black race. The principal presenting feature was a painful erection without sexual contact. Idiopathic priapism was the most prevalent, although the sickle cell anemia was an important etiological factor. The surgical technique most commonly used was the cavernospongiosal shunt. Intracavernosal injection of phenylephrine was the treatment of choice for pharmacological priapism. Seven patients had erectile dysfunction.

[Acquired ichthyosis caused by bladder neoplasia. Presentation of the 1st case in Cuba].

Ichthyosiform dermatoses comprise a heterogeneous group of cutaneous disease characterized by keratin disorder that clinically manifests as dry, rough and scaly skin. The acquired form of ichthyosis has principally been associated with neoplastic disease. It has also been described in association with other disorders and as drug-induced cutaneous manifestations. We report on a patient with a bladder tumor who developed acquired ichthyosis, a complication and presenting feature of the underlying neoplastic condition. The clinical manifestations and associated conditions are described. To our knowledge, this is the first case of acquired ichthyosis from a bladder tumor reported in Cuba.

[Bilateral abscess of the psoas and systemic lupus erythematosus].

Herein we describe a patient with systemic lupus erythematosus and bilateral psoas abscess, an uncommon condition caused by septic metastases from ulcerous necrotic lesions involving both lower limbs. We describe the clinical features and the complementary work up, which included ultrasound. Similarly, treatment is described, as well as the results yielded by bacteriologic analyses of pus specimen. The literature is reviewed, highlighting the most important criteria.

[Fine-needle aspiration cytology in the diagnosis of prostate cancer. Results].

OBJECTIVE: To demonstrate the utility of fine needle aspiration biopsy in the diagnosis of prostatic tumors, basically carcinoma of the prostate. METHODS/RESULTS: The clinical records of 497 patients who underwent fine needle aspiration biopsy were reviewed. Age, skin color, clinical diagnosis by DRE, transrectal core biopsy, correlation between clinical and histological diagnosis, distribution according to type of adenocarcinoma, correlation between cytological and histological diagnosis, and complications were analyzed. Of the 497 patients, 162 had histological confirmation. Of these 162 patients, the Galen and Gambino statistical method was utilized in 132 which represented the true negatives and positives. Sensitivity was 86%, specificity 96%, positive predictive value 91%, negative predictive value 93%, and efficiency was 92%. The complication rate was low. CONCLUSIONS: Fine needle aspiration biopsy is a safe and efficient diagnostic method in prostatic tumors and causes minimal discomfort to the patient.
