[Polypoid cystitis in pregnant diabetic]. / Cistitis polipoidea en diabética embarazada.

Presentation of one case of a diabetic patient, who after 8 weeks pregnancy presented polypoid cystitis, with no prior background of vesical catheterism. The rarity of the case, as well as the clinical and pathoanatomical characteristic are commented.

[Permanent endoprostatic prostheses in patient with obstruction caused by benign hyperplasia of the prostate]. / Prótesis endoprostáticas permanentes en pacientes con obstrucción por hiperplasia benigna de próstata.

Presentation of the results obtained using the intraprostatic prosthesis UroLume in 78 patients wit BPH obstruction, 69 of which presented high surgical risk (ASA IV). Mean age was 79.8 years (r: 62-93). All patients carried urethral catheters, except 4 (5.1%) who had a provisional metal coil that required replacement. Prosthesis were implanted successfully in 72 cases (93.3%). The most significant exclusion criterion was an excessive length of prostate urethra. Mean follow-up was 15.3 months (r: 3-38). Mean maximum flow at 1 year after implant was 12.7 mL/sec; mean symptoms score (I-PSS score) was 6.2 points and in most prosthesis, epithelization had taken place. Three patients required implant of another prosthesis, either during the same surgical procedure (1 case) or later due to retention or dysuria (2 cases). Due to acute urine retention (AUR) during the immediate postoperative, resection of the middle lobe was performed in one case while a second case required late resection of intraluminal hyperplastic tissue. Three patients (4.1%) had haematuria that forced hospital admission some months after the implant, and three cases (4.1%) required removal of the prosthesis; at patient's request (1 case), due to calcification (1 case) and for stress incontinence (1 case). After a follow-up of over three years, it can be concluded that the UroLume prosthesis is an effective alternative to TUR in patients at high surgical risk.

[Paratesticular lipoma]. / Lipoma paratesticular.

In spite of being the most frequent benign tumour of the spermatic cord, absolute frequency of this neoplasia is very low. We discuss here a case report of an spermatic cord lipoma with several years evolution. Although ultrasound is useful for clinical diagnosis, exploratory scrototomy and surgical exeresis of the mass is the only reliable diagnosis and viable treatment.

[Renal agenesis, cranial blind ureter and ureterocele. Report of a case]. / Agenesia renal, uréter ciego craneal y ureterocele. A propósito de un caso.

OBJECTIVES: We report a case of associated malformations in a young male with recurrent epididymitis. METHODS: In our study we used the following techniques: ultrasound, intravenous urography, retrograde pyelography, computed tomography and cystoscopy. RESULTS: We observed three coexisting congenital malformations: renal agenesis, cranial blind-ending ureter and ureterocele. CONCLUSIONS: Different urologic malformations are usually found in association. In our view only symptomatic ureteroceles require treatment.
