RESUMEN
To evaluate the Oncological and functional results and to clear risk factors of biochemical recurrence in patients with prostate cancer treated by retropubic prostatectomy. Retrospective analysis of 50 consecutive retropubic radical prostatectomies performed between January 1999 and January 2008. Biochemical recurrence was defined by PSA > 0.2 ng/ml. Univariate analysis of prognostic factors of biochemical recurrence was performed. The study of the urinary continence and the sexuality is essentially based on a meticulous interrogatory. The biochemical recurrence-free survival was 68%. Significant risk factors on univariate analysis were: number of positive biopsy, the percentage of positive biopsy, perineural invasion, Gleason score, clinical stage, pathological stage, and tumour volume. On the functional plan, only one patient is totally incontinent. The return to a normal sexuality appears uncertain, the sexual potency was satisfactory among 5 patients [10% of the patients operated and 55,5% of the patients having had a nervesparing techniques]. Our oncoligical results are acceptable and are quite comparable to literature. This while guaranteeing the satisfactory functional results essentially basing on an acquirement of a continence quasi-perfect
RESUMEN
Background: The Resonance ureteral stent is a newly developed all-metallic double-pigtail ureteral stent allowing a palliative diversion on a patient with malignant ureteral obstruction
Aim: To define selection criteria of good candidates for Resonance stent
Case: A 62-year-old woman was admitted to the emergency department with complaining of severe right flank pain and anuria. Twelve days earlier, we had placed retrogradely a ureteral metallic Resonance stent [Resonance: Cook Ireland Ltd, Limerick, Ireland] for the treatment of a ureteral compression from pelvic recurrence of an appendical colloid mucosal carcinoma in a solitary functionning right kidney. A percutaneous nephrostomy catheter was placed, and an antegrade nephrostogram demonstrated complete distal ureter obstruction. The patency of the ureteral stent was restored spontaneously and then, nephrostomy catheter was removed. Two weeks later, she presented with obstructed ureteral stent. Percutaneous nephrostomy was performed and Resonance stent was removed definitively. Ureteroscopy with biopsy confirmed the tumor extension into the ureteral lumen
Conclusion: The risk of subsequent obstruction after Resonance metallic ureteral stent placement is real. Patients with intra-ureteral tumour extension are presumably not good candidates for Resonance stent management
