    Urology. 2007 Jan;69(1):27-31; discussion 31-3. Emergency ureteroscopic management of ureteral stones: why not? Osorio L, Lima E, Soares J, Autorino R, Versos R, Lhamas A, Marcelo F. Department of Urology, Santo Antonio General Hospital, Oporto, Portugal. luis_osorio@netcabo.pt Abstract OBJECTIVES: To describe a single-center experience in the emergency ureteroscopic management of ureteral stones. METHODS: We retrospectively considered the data from 144 patients (mean age 49.6 years, range 23 to 82) who had had obstructive ureteral stones and had undergone emergency ureteroscopy with stone retrieval. Intracorporeal pneumatic lithotripsy was performed when necessary. At the end of the procedure, a ureteral catheter was systematically left in place in 100 patients (69.4%) and removed within 24 hours. In the remaining 44 patients, a double-J stent was preferred and was removed within 30 days, depending on the clinical course. Stone-free status was defined as the complete absence of fragments at 1 month of follow-up. RESULTS: The calculi were more frequently localized in the distal ureter than in the proximal one (90.3% versus 9.7%, respectively). The overall mean stone diameter was 9.1 mm (range 5 to 20). The overall stone-free rate was 92.4%. A greater stone-free rate was obtained in those with stones less than 10 mm (95.8%) than in those with stones larger than 10 mm (89%, P = 0.002). Similarly, a significantly better outcome occurred for those with stones located in the distal ureter (94.6%) than for those with stones in the proximal one (71.4%, P = 0.004). The overall complication rate was 4.2%. The mean hospital stay was 2.5 days (range 1 to 7). CONCLUSIONS: In our experience, emergency ureteroscopy in cases of obstructive ureteral stones proved to be safe and effective. It has the main advantage of offering both immediate relief from pain and stone fragmentation. Additional extensive studies are warranted to corroborate these findings.

  • Hematuria after ureteraliliac
    Publication . PALACIOS, A.; MASSO, P.; OSORIO, L.; OLIVEIRA, A.; SOARES, J.; MARCELO, F.
    Arch Esp Urol. 2006 Apr;59(3):287-9. [Hematuria after ureteral-iliac aneurysm rupture] [Article in Spanish] Palacios A, Massó P, Osorio L, Oliveira A, Soares J, Marcelo F. Servicio de Urología, Hospital General de Santo Antonio, Porto, Portugal. aphmmx5@hotmail.com Abstract OBJECTIVE: Ureteral-iliac artery fistula is a rare condition. We perform a bibliographic review and report a case of ureter-iliac artery fistula reviewing its major differential diagnosis. METHODS: This case-study describes a patient with massive hematuria that presented a ureter-iliac artery fistula secondary to spontaneous rupture of an internal iliac artery aneurysm. RESULTS: 86 -year-old male patient with history of previous surgery for aneurysm and ureteral catheterization. CONCLUSIONS: This difficult diagnosis should be thought of in a patient with massive macroscopic hematuria and previous vascular surgery. The treatment is always surgery.

  • Penile abscess. Case report
    Publication . PALACIOS, A.; MASSO, P.; VERSOS, R.; OSORIO, L.; CARVALHO, L.F.; SOARES, J.; MARCELO, F.
    Arch Esp Urol. 2006 Oct;59(8):809-11. [Penile abscess. Case report] [Article in Spanish] Palacios A, Massó P, Versos R, Osorio L, Carvalho LF, Soares J, Marcelo F. Servicio de Urología, Hospital Geral de Santo Antonio, Porto, Portugal. aphmmx5@hotmail.com Abstract OBJECTIVE: To report one case of penile abscess, with special reference to diagnostic and therapeutic aspects. METHODS: One case of penile abscess is presented in a patient referred for penile swelling. RESULTS: During surgical exploration it showed to be a corpora cavernosum rupture with drainage of a small volume of purulent fluid. CONCLUSIONS: Penile abscess is uncommon. High frequency ultrasonography is a reliable diagnostic imaging method. We were able to incise the affected area of the corpus cavernosum and glans safely, and with appropriate antibiotics this patient was treated successfully.

  • Tubulovillous adenocarcinoma of the renal pelvis. Case report
    Publication . PALACIOS, A.; LIMA, O.; MASSO, P.; OSORIO, L.; VERSOS, R.; SOARES, J.; MARCELO, F.
    Arch Esp Urol. 2006 Nov;59(9):916-9. [Tubulovillous adenocarcinoma of the renal pelvis. Case report] [Article in Spanish] Palacios A, Lima O, Massó P, Osório L, Versos R, Soares J, Marcelo F. Servicio de Urología, Hospital Geral de Santo Antonio, Porto, Portugal. aphmmx5@hotmail.com Abstract OBJECTIVE: To present a case of tubulovillous renal pelvis adenocarcinoma. METHODS/RESULTS: An 81 year-old patient presented at Emergency Department with sepsis. CT scan showed a staghorn calculus with signs suggestive of pyonefrosis. A nephrectomy was performed and pathological exam revealed tubulovillous renal pelvis adenocarcinoma. CONCLUSIONS: Renal pelvis adenocarcinoma is a rare disease. It is usually accompanied by chronic urinary infections, on inflammatory state and staghorn calculi. The best therapeutic option is nephrectomy and the prognosis is poor.
