Zephyr 375 urinary sphincter implant by unical perineal incision. Initial experience.

The treatment of male severe stress incontinence (MUI) after surgery is the implantation of an artificial urinary sphincter (AUS). Traditionally you need two incisions: perineal and inguinal. Our objetive is present a series of patients treated with the Zephyr 375 EUA implant through a single perineal incision. We present six men operated on for MUI after Transuretral resection of the prostate (TURP) (1) and radical prostatectomy (5). Preoperatively we perform Pad-Test and cystoscopy. Under epidural anesthesia, a vertical perineal incision was made and dissection up to the bulbospongiosus muscle was divided and we dissected the bulbar urethra. After removing the probe, we place the cuff, checking that it reaches the appropriate pressure, leaving it deactivated. To place the pump-reservoir, we digitally develop a scrotal dartos pocket from the perineum that we close with Vicryl 3/0. After closing the muscle with 3/0 Vicryl, we left a suction drain and a bladder catheter. The mean age was 63 years (55-72). Mean surgical time was 68 minutes (60-85). All were discharged the next day without catheter and drain. All patients comfortably palpated the scrotal reservoir-pump. After activation, all patients were continent without needing additional adjustment, using 3 a safety pad. The degree of satisfaction was very high, all of them affirmed that they would undergo the same intervention again. The Zephyr 375 urinary sphincter allows placement through a single perineal incision, reducing surgical time, simplifying the technique, and reducing morbidity without compromising the functional outcome.

[Rescue cryotherapy for prostate cancer after radiotherapy]. / Crioterapia de rescate en el cáncer de próstata después de radioterapia.

Radical Radiotherapy constitutes a useful therapeutic option for localized prostate cancer. Almost one third of prostate cancer patients choose this alternative to treat the disease. Despite modifications in the technique as intensity modulation, 3D conformational radiotherapy or computer-assisted brachytherapy, a significant percentage of these patients will show an increase in PSA values after radiation. Local relapse without distant disease and PSA less than 10 ng/ml are candidates for salvage therapy. Cryotherapy has already become a curative treatment option in this group of patients. Recent technological as well as surgical advances in salvage-cryotherapy have reduced dramatically complications and progressively increase the interest on this alternative.

Primary renal Ewing's sarcoma.

OBJECTIVE: To report two new cases of Ewing's sarcoma/primitive neuroectodermal tumor of the kidney, one of them with tumor thrombus in cava. METHOD: Characterization of two new cases and literature review by PubMed search. RESULTS: We report the cases of two men diagnosed with primary renal Ewing's sarcoma, who have been treated with nephrectomy and adjuvant chemotherapy, being in complete remission to date. CONCLUSION: Ewing's sarcoma / primitive neuroectodermal tumor of the kidney is a rare condition that mainly affects young adults. The natural history of these tumors is the evolution towards metastatic disease and death. Treatment is multimodal, combining surgery and chemotherapy. The role of radiotherapy is not well established.

Metastatic prostate cancer on the thyroid cartilage: unusual symptoms of prostatic adenocarcinoma. Case report.

OBJECTIVE: To review the unusual localizations of metastasic prostate cancer with the contribution of a clinical case of prostatic adenocarcinoma metastasis in the thyroid cartilage. METHODS: 49-year-old-male admitted with history of 48 hour hematuria associated with lumbar pain radiating to the lower extremities and cervical tumour for 3 months. RESULTS: CT scan of the thorax, abdomen and pelvis was performed showing an insufflating lesion on the left thyroid cartilage lamina suggesting chondrosarcoma, a 4 cm tumour on the posterior side of the bladder, and metastases on L4-S1 vertebral bodies and left iliac bone. Cystoscopy revealed an image on the posterior vesical wall suggesting prostatic infiltration by a tumoral process without evidence of urothelial tumors. PSA was 617 ng/ml. Digital rectal examination: Prostate with augmented consistency. Due to these results an ultrasound-guided transrectal prostatic biopsy was performed with the pathological result of Gleason 8 prostatic adenocarcinoma involving boths lobes. Complete androgen blockade with Bicalutamide and Goserelin was started with good response lowering the PSA level down to 29 ng/ml. Regarding the cervical mass suggestive of thyroid chondrosarcoma a left vertical partial laryngectomy was performed with replacement of the thyroid cartilage by septal cartilage. Pathological study of the piece revealed the presence of prostatic adenocarcinoma. CONCLUSION: Metastatic prostate cancer in the thyroid cartilage is exceptional, there being only five cases described in the literature. This fact, linked to the scant frequency of tumours lying in this cartilage and diagnosis by means of radiological suspicion, makes it very difficult to include metastatic prostate cancer in the routine differential diagnosis of cervical masses.
