Evaluation of prenatally diagnosed hydronephrosis by morphometric measurements of the kidney.

A large number of hydronephrotic kidneys (108) were diagnosed prenatally in 69 infants between 1987 and 1991 and subsequently confirmed postnatally. Prenatal morphometric measurements were done in order to find reliable parameters for the detection of a group at risk for surgical treatment. A second aim of the study was to describe the natural history and management of hydronephrosis detected prenatally. We devised a classification of postnatal obstructive uropathy using ultrasonography and the renal scan. Accordingly, we classified the patients as having mild, moderate or severe hydronephrosis. A renal pelvic antero-posterior diameter (APD) of 9 mm or more, and a pelvic-to-renal APD ratio of 0.45 before 32 weeks of gestation and 0.52 thereafter, were found to be useful for the detection of severe outcome. Our new parameter, a pelvic-to-renal volume ratio of greater than 0.08, can also be used for this purpose.

Regional anaesthesia for circumcision in adults: a comparative study.

Penile block (PB) in adults is not a well-recognized technique. The aim of this study was to compare, in a randomized prospective manner, five different techniques of PB in 250 adults undergoing circumcision with regard to anaesthetic quality, complications and postoperative analgesia. Patients were divided into five groups (50 per group) according to the technique used: Group A--"10, 30-13, 30" approach; Group B--the subpubic approach; Group C--subcutaneous ring block; Group D--a combination of frenulum infiltration and the "10, 30-13, 30" approach; Group E--a combination of frenulum infiltration and the subpubic approach. The number of failed blocks in Groups A and B (41 and 43 respectively) was greater than in Groups C, D and E (2, 3 and 5 respectively) (P < 0.001). The five groups did not differ with regard to adverse effects or time until the onset of postoperative pain when the blocks were successful. It is concluded that good surgical anaesthesia, a low rate of adverse effects and prolonged postoperative analgesia can be achieved by the use of either subcutaneous ring block or a combination of dorsal nerve block (using the "10, 30-13, 30" or the subpubic approach) and infiltration of the frenulum. These approaches to the PB are effective anaesthetic techniques for circumcision in adults.

Ultrasound-guided aspiration for relief of pain generated by simple ovarian cysts.

Over a 2-year period, ultrasound-guided aspiration of painful, presumptively benign ovarian cysts was performed in 18 women < 40 years old. Aspiration was performed either transvaginally (12 patients) or transabdominally (6 patients) depending on the cyst location. Neither anaesthesia nor analgesia were used, and all patients had immediate pain relief, and escaped immediate surgical intervention. None had complications or evidence of malignant cells on cytologic examination, and all were discharged within 24 h of the procedure. The recurrence rate within 1 year of the procedure was 11.1%. The procedure appeared to be a good and safe alternative to surgery.

The accuracy of endometrial Pipelle sampling with and without sonographic measurement of endometrial thickness.

OBJECTIVE: To evaluate the accuracy of Pipelle endometrial sampling with and without sonographic measurement of endometrial thickness. METHODS: We studied prospectively 176 consecutive patients (23% after and 77% before menopause) scheduled for D&C. Sonographic measurement of the endometrium and endometrial biopsy with the Pipelle were performed before the curettage. RESULTS: In 159 cases (90%), the endometrial histologic results of curettage agreed with those of the Pipelle biopsy. All three cases of endometrial cancer were identified by Pipelle aspiration. In seven cases (4%), the Pipelle aspiration failed to detect hyperplasia. Sonographic endometrial thickness of more than 5 mm slightly increased the sensitivity and slightly decreased the specificity of Pipelle aspiration from 82 to 92% and from 99 to 96%, respectively. In postmenopausal patients admitted for bleeding, the sensitivity and specificity reached 100%. CONCLUSIONS: Our data suggest that normal Pipelle aspirates in premenopausal patients with abnormal uterine bleeding are highly accurate. In postmenopausal patients with sonographic endometrial thickness of 5 mm or less, the accuracy reached 100%.

[Chorionic villi sampling: choice of transcervical or transabdominal routes preferable to use of transcervical route exclusively].

Between November 1985 and June 1990 we performed 400 first trimester chorionic villi samplings (CVS). In the first 107 cases only transcervical CVS was performed, regardless of placental location. Later, 163 transcervical and 130 transabdominal CVS were performed, depending on placental location. Anterior and fundal placentas were approached transabdominally and posterior placentas transcervically. Multiple pregnancies were excluded. Successful results were obtained in 394 out of 400 cases. There were 5 failures in the first set of cases and 1 in the second (p < 0.05). In 14 cases (3.5%) fetuses with normal karyotypes were spontaneously aborted, 5 of these in the first period (4.7%) and 9 (3.1%) in the second. The spontaneous abortions in the second period followed transabdominal CVS in 4 cases out of 130 (3.1%) and the transcervical route in 5 cases out of 163 (3.105%). The average attempts per case in the first period was 1.44 (SD 0.66) while in the second it was 1.17 (SD 0.44, p < 0.0001) for the transcervical route and 1.06 (SD 0.2, p < 0.002) for the transabdominal route. In our experience choosing between transabdominal and transcervical CVS according to placental location is preferable to the sole use of transcervical CVS in terms of lower failure rate and fewer attempts per case. Proficiency in both techniques is mandatory for optimal results.

Leiomyosarcoma of the bladder - ultrasonographic features.

We present a case in which the evaluation of a bladder mass revealed a leiomyosarcoma of the bladder. The ultrasonographic appearance of this tumor is described for the first time. Leiomyosarcoma of the bladder, although rare, should be considered in the differential diagnosis of pelvic masses.

Aspiration of ectopic pregnancy under guidance of vaginal ultrasonography.

This case report describes the treatment of tubal pregnancy by aspiration of the gestational sac content and injection of methotrexate by transvaginal sonographic guidance. The confirmation of the embryo aspiration as indicated by disappearance of the embryo with its heart beat and the resulting 46,XY karyotype, raises the question whether methotrexate injection is necessary.

Chorionic villus sampling and selective termination of a chromosomally abnormal fetus in a triplet pregnancy.

Transabdominal chorionic villus sampling (CVS) was performed on a patient with a triplet pregnancy. The karyotypes were as follows: 46,XX; 46,XY; and 46,XY/47,XXY. Selective termination was done on the affected fetus successfully by intrathoracic potassium chloride (KCl) injection. Amniocentesis which was performed at the same time confirmed the CVS results, showing the same mosaic findings. Following the procedure, the pregnancy proceeded uneventfully and two normal newborns were delivered at term.

Self-induced abortion--the peril is still real.

A new immigrant from Romania tried to induce abortion by intrauterine self-administration of hypertonic sucrose at 7 weeks' gestation. Complete abortion did not occur and bleeding, infection and pregnancy residua persisted for 13 weeks. Evacuation by uterine curettage had failed, but a second curettage under real-time sonographic guidance was successful. Self-induced chemical abortions are rarely encountered in modern medicine. However, elevation of the iron curtain and mass immigration may increase the frequency of self-induced abortions in Western countries. Since the management, course, and outcome of each type of self-induced abortion are somewhat different, the pertinent differentiation is between chemical and mechanical and between various agents used for chemical-induced abortions. Mechanical abortions are best treated 12 to 24 hours after antibiotic therapy, while in chemically-induced abortion early evacuation of the uterus is indicated.

Early pregnancy termination: an improved technique for 'menstrual regulation' with ultrasound assistance.

We performed aspiration of early pregnancy on 100 women requesting termination, using a low caliber angled catheter under sonographic guidance, without analgesia or anesthesia. The sonographic inclusion criteria for the study were: (1) mean gestational sac diameter less than 30 mm, or (2) crown rump length less than 10 mm when an embryo was visualized. The uterine content was successfully evacuated in all cases and none needed an additional curettage. Two women developed mild endometritis which responded to antibiotic therapy. This refinement of this 'menstrual regulation' technique seems to be safer when compared with the reported results of the original technique.

Persistent gestational trophoblastic disease following evacuation of a tetraploid partial hydatidiform mole.

A 31-year-old woman at 11 weeks gestation with ultrasonographic demonstration of partial mole had markedly elevated serum bHCG levels (458,000 mIU/ml). The patient underwent a vacuum curettage with pathological confirmation of the diagnosis, and cytogenetic analysis revealed a tetraploid karyotype (92,XXXX). The patient developed persistent gestational trophoblastic disease and was successfully treated with two courses of actinomycin D. Persistent trophoblastic disease after evacuation of a tetraploid partial mole was not reported previously.

Spontaneous ovarian hyperstimulation syndrome concomitant with spontaneous pregnancy in a woman with polycystic ovary disease.

Ovarian hyperstimulation syndrome has been described after treatment with exogenous gonadotropins, clomiphene citrate, and gonadotropin-releasing hormone. Spontaneous ovarian hyperstimulation syndrome has not been described before, except in association with hypothyroidism. We report on a case associated with spontaneous pregnancy, occurring in a woman with polycystic ovary disease.
