Laparoscopic partial cystectomy in the management of bladder endometriosis: report of two cases.

Endometriosis is the proliferation of endometrial tissue outside the normal confines of the myometrium or uterine cavity. Endometriosis involving the urinary tract occurs in approximately 1% to 2% of cases. The bladder is affected in 80% of these patients. The diagnosis of vesical endometriosis is difficult, and it should be confirmed by cystoscopy with biopsy. Laparoscopic examination represents the gold standard for the diagnosis of pelvic endometriosis. Urinary bladder endometriosis may be treated surgically or medically with hormone-suppressive therapy. However, medical treatments usually are only palliative, and symptoms generally recur on discontinuation. We report our experience in two patients with vesical endometriosis who were managed successfully with cystoscopy-assisted laparoscopic partial cystectomy.

[Transperitoneal laparoscopic bladder diverticulectomy].

OBJECTIVES: To report the first case of bladder diverticulectomy in a female patient. METHODS: 74-year-old female patient with a two-year history of recurrent lower urinary tract infection and the diagnosis of big bladder diverticulum. A laparoscopic bladder diverticulectomy was performed. RESULTS: Operative time was 90 minutes. The patient had a satisfactory outcome with the drainage being retrieved on postoperative day three and discharged home the same day with bladder catheter. The catheter was retrieved on postoperative day 7. Cystography showed a normal bladder without diverticulum. CONCLUSIONS: We considered that laparoscopic surgery of the bladder diverticulum is an alternative, completely comparable to classic surgery, and it should be considered an option in the management of bladder diverticula requiring surgery.

[Concordance of Gleason histological scoring for prostatic cancer in needle biopsies and the surgical piece obtained during radical prostatectomy].

BACKGROUND: The Gleason histological score is an independent prognostic factor in prostate cancer that helps in therapeutic decisions. AIM: To analyze the concordance between the Gleason score of needle prostatic biopsy and the score from the study of the surgical piece obtained during radical prostatectomy. MATERIAL AND METHODS: Retrospective analysis of 212 cases of prostate cancer, diagnosed between February 1993 and March 2003. All had the Gleason histological scores from needle prostatic biopsies and in the surgical piece obtained during radical prostatectomy. All pathological studies were done by the same observer. RESULTS: There was an exact concordance of Gleason scores between needle biopsy and the surgical piece in 49% of cases and a concordance of +/- 1 unit in 89%. The concordance improved in the second half of the study period. No cases with a Gleason score of less than 5 were detected since 1999 in the surgical piece. CONCLUSIONS: The concordance of Gleason score of needle prostatic biopsies and surgical pieces is good. This concordance increases with the experience of the pathologist.
