The value of hysteroscopic exploration for abnormal uterine bleeding.

STUDY OBJECTIVE: To determine sensitivity, specificity, positive predictive value, negative predictive value, and global diagnostic precision of hysteroscopic exploration in the diagnosis of endometrial hyperplasia and adenocarcinoma in women with abnormal uterine bleeding. DESIGN: Retrospective analysis. SETTING: University-affiliated hospital. PATIENTS: One thousand three hundred ninety-eight patients with abnormal uterine bleeding, 57.3% premenopausal and 42.6% postmenopausal. INTERVENTIONS: Diagnostic hysteroscopy and subsequent dilatation and curettage. MEASUREMENTS AND MAIN RESULTS: Endometrium was classified hysteroscopically as normal, atrophic, endometrial hyperplasia, and endometrial carcinoma. Histopathologic diagnosis was performed to determine the efficacy of hysteroscopy in diagnosing endometrial hyperplasia and adenocarcinoma. For endometrial hyperplasia in premenopausal women, sensitivity was 71.8%, specificity 96.4%, and global diagnostic precision 92.5%; in postmenopausal women, respective figures were 85. 1%, 100%, and 97.3%. For diagnosing adenocarcinoma in premenopausal patients, hysteroscopy was 100% sensitive, with specificity 99.4% and global diagnostic precision 99.5%; in postmenopausal women, respective figures were 100%, 99.4%, and 99.5%. CONCLUSIONS: In women with abnormal uterine bleeding, diagnostic hysteroscopy is a basic tool that allows precise diagnosis of endouterine lesions such as polyps and submucous myomas. It also is highly accurate for evaluating endometrial adenocarcinoma and hyperplasia.

[Ultrasonographic (intra- and extraluminal) pattern of cervico-urethral anastomosis after radical prostatectomy]. / Patrón sonográfico (intra y extraluminal) de la anastomosis cérvico-uretral tras la prostatectomía radical.

Thirteen patients, mean age 61 years (range 54 to 71), diagnosed with prostate adenocarcinoma underwent radical prostatectomy. To achieve a diagnosis they were all performed blood PSA determination, digital rectal examination, transrectal ultrasound and a prostate ultrasound-guided biopsy by automatic gun puncture. Serum PSA quantification, digital rectal examination and transrectal ultrasound were repeated in the immediate post-operative, and three and six months after surgery. Through the information obtained with endocavitary ultrasound, the lumen of the cervicourethral anastomosis and the perianastomotic tissue was assessed. Transrectal ultrasound plays a relevant role in the follow-up of patients undergoing radical prostatectomy. When a patient with prostate radical surgery shows an elevation of serum PSA and/or abnormal digital rectal examination, an ultrasound-guided biopsy (at the node or perianastomotic area) is indicated.

[Ureterosigmoidostomy detubularized with surgical staplers: C.F.C. (Original technique)]. / Ureterosigmoidostomía destubulizada mediante súturas mecánicas: C.F.C. (Técnica original).

Description of our modification of the detubulized ureterosigmoidostomy surgical technique (Castiñeiras-Ferragut-Camacho). In an attempt to shorten the surgery time, we used for these changes absorbable mechanical sutures (Poli Gia and T.A.). This paper analyzes the technical details of interest as well as the anatomicosurgical considerations that should be known prior to carry out this type of by-pass. The anatomicophysiological principles on which our developments are based are those referred by N.G. Kock15 and used by R. Hohenfellner and R. Fisch14, when they described the detubulized ureterosigmoidostomy performed manually. We believe that both surgical procedures, R. Hohenfellner & R. Fisch14 and ours (detubulized ureterosigmoidostomy, C.F.C.), are suitable alternatives to conventional ureterosigmoidostomy.

[Complications of ultrasound-guided transperineal puncture biopsy of the prostate]. / Análisis de las complicaciones de la punción-biópsica transperineal ecodirigida de próstata (P.B.T.E.P.).

Between June 1988 and February 1993, 520 ultrasound-guided transperitoneal prostate biopsy punctures were performed in patients with prostate disease. Of these, 89 (17.1 %) were positive for malignancy. An analysis is made of the highly uncommon complications observed, which corresponded to 17 cases of haematuria (3.26%) and 3 of fever (0.5%). Likewise, reference is made to perineal neoplastic implantation, since such complication was evident in one of the cases contributed (0.19%). Also, a review of the literature relative to the complications is made, concluding by stating the relevance of this diagnostic technique in spite of said complications.
