A case is presented in which massive uterine hemorrhage in early pregnancy is successfully controlled by bilateral uterine artery ligation. A 26-year-old white woman, gravida 3, para 1, abortus 2, was admitted 8 days following an elective abortion because of heavy bleeding and a low grade fever which failed to respond to Ergotrate and tetracycline. Although bilateral ligation is not the answer to all problems of bleeding from the uterus, it is superior to most other procedures, and physicians providing obstetric care should be familiar with the technique. The vessels can be easily identified, and the ureter and bladder are outside of the operative field. Although bleeding may continue from ovarian collateral vessels, the success rate is 90% with most of the failures being associated with placenta previa or placenta accreta. There are no short or long term complications.

A recent U.S. Public Health Service report compared the incidence of complications with 3 methods of midtrimester abortion. The comparison was based on a 4-year study of abortions done in 32 institutions. Major complications were least frequent with cervical dilatation followed by curettage or suction evacuation, more frequent with hypertensive saline injected into the amniotic sac, and most frequent with instillation of prostaglandin F2. By the second trimester, dilatation and evacuation is a difficult procedure. Major complications considered were: fever for 3 or more days; pelvic infections; pneumonia; thrombophlebitis; hemorrhage requiring transfusions; psychiatric hospitalization; hypernatremia; injury to bladder, ureter, or intestines; wound disruption; unintended major surgery; pulmonary embolism; convulsions; endotoxic shock; cardiac arrest; and death. The report is difficult to evaluate. Most medical letter consultants prefer intraamniotic administration of prostaglandin F2 or saline for midtrimester abortions.

A case of chorioadenoma destruens with uterine rupture is reported. The patient was admitted because a persistent uterine bleeding after abortion about two months before. The titulation of gonadotrophic hormone resulted in 25,000 unities. After curettage she was complicated with hemoperitoneum and went to surgery. During hysterectomy were identified trophoblastic tissue in the broad ligament and partial blocking of the right ureter. After repeated chemotherapy she presented severe immuno depression and sepsis complicated with hemopericardium and died five months after the first admission. The pathology study demonstrated a perforation because a trophoblastic invasion in the right side of the cervix and in the autopsy was demonstrated right ureteral obstruction due to a fibro necrotic an inactive trophoblastic tissue determining significant right hydro-uretero nephrosis.

We performed extracorporeal shock wave lithotripsy (ESWL) to 5 solitary kidney patients with upper urinary tract stones (4 kidneys and 1 lower ureter) using the EDAP lithotripter LT-01 and achieved 4 complete and 1 well results. The size of stones ranged from 8 mm to staghorn and trials were 1 to 10 units. We could accomplish perfect crushing and abortion of stones in the 4 renal stone patients without any adjuvant systems as ureteral stent but nephrostomy was needed in the 1 lower ureteral stone patient developed anuria. The values of blood pressure, hematology, blood chemical constituents and urine excretion enzymes at a month after the last ESWL were not so changed compared with those of preoperation and also excretory urogram showed favorable findings. In this series decreased renal functions by ESWL were not observed. We confirmed ESWL was an effective and a safe method even in the cases of solitary kidney patients and monotherapy without any adjuvants was possible.

During the period from (May 1980 to July 1985), six cases of rudimentary uterine horn complicating pregnancy were presented. Artificial abortion failed in five cases, one case complained of lower abdominal mass only. The other 5 cases were correctly diagnosed preoperatively. In one case the pregnant horn ruptured with profuse internal haemorrhage and deep shock. The horn cavity was separated from the normal uterine cavity by a connective tissue cord in all 6 cases. Two of the cases had dysmenorrhea and congenital abnormally of ureter in the same side of the rudimentary horn. Diagnosis was discussed in detail B-ultrasound scanning is useful for the early diagnosis of rudimentary horn pregnancy. The rudimentary horn should be resected together with the fallopian tube on the same side with preservation of ovary. Its round ligament must be cut and fixed to the normal uterus.

Forty patients with ureterolithiasis were studied to evaluate the efficacy of a continuous epidural block with local anesthetics. The patients were randomly allocated into 3 groups: first group (n = 7) received continuous epidural administration of 1% mepivacaine at a rate of 2 ml.hr-1; second group (n = 19) received intermittent bolus administration of the same anesthetic 4-5 times daily; and third group (control group, n = 14) was treated by conventional therapy including infusion of Ringer's solution and diuretics. Among 3 groups, a comparison of the rate of abortion of ureter stone, the rate of mobilization of stone, and the frequency of operation was performed. The rate of abortion in group 1 was significantly higher than those of group 2 and control. The rate of mobilization of stone in group 1 tended to be higher than group 2 and control. Also the frequency of operation in group 1 tended to be lower than group 2. Effect of continuous administration with 1% mepivacaine in patient with ureterolithiasis was comparable to that of intermittent bolus administration of 2% mepivacaine or 0.5% bupivacaine reported. We conclude that the continuous block with 1% mepivacaine is effective and safe for treating the patient with ureterolithiasis.

Of 18 pregnancies in 11 renal transplant recipients, three were terminated and in the remaining 15 (in 8 women) there were 10 live births (including one set of twins), five intrauterine deaths, and one spontaneous abortion. Graft function deteriorated in six women, from obstruction of the transplanted ureter in two, recurrent glomerulonephritis in two, rejection in one, and pelvi-ureteric junction obstruction in one. Hypertension worsened or developed in all but one of the pregnancies and proteinuria appeared in eight. Of the 10 live births only one reached 38 weeks gestation (mean 35 weeks) and four neonates were small for gestational age. One infant died early from intraventricular hemorrhage and hyaline membrane disease, one fetus had hydrocephalus, and the others were normal. Factors associated with a poor fetal outcome were deterioration in graft function during pregnancy, pre-existing hypertension, or the development of hypertension before the third trimester.

Case report on a patient with an extensive dilatation of renal pelvis and ureter during the first and the following two pregnancies. Operative drainage was performed of renal pelvis on both sides in the 24th and 28th week of the first pregnancy. The second pregnancy ended with spontaneous abortion in the 27th week of pregnancy. Percutaneous punction nephrostomy with successful course of the third pregnancy. Drainage of renal pelvis by punction nephrostomy is indicated in case of co-existence between dilatation of renal pelvis and severe illness and destruction renal parenchyma and of septic pyelonephritis in pregnancy. This procedure should also be done in case of a solitary kidney and excessive dilatation of the renal pelvis. An operative approach is recommended in renal abscess.

The higher level of patients of pregnant woman in comparison with non-pregnant ones results from a higher unfitness for work which nearly corresponds to the increase of sicknesses depending on gestation. From all causes of unfitness for work more than 60% were depending on gestation. Causes for the half of the release from work depending on gestation were the three diagnoses threatening abortion, threatening premature birth and bleedings. On the total level of patients of 11.66% they had a share of 5.70% points. Infections of the ureter, the diagnosis' 'Other complications in pregnancy', hyperemesis and gestoses followed. Infections of the upper respiratory tract and influenza were the causes of all releases from work which were not depending on gestation. Their share on the level of patients amounted to 0.9% points. Releases from work because of sicknesses of circulation and of the digestive tract followed in their frequency. A number of further causes of unfitness for work had only a small share on the happenings of unfitness for work.

Research on the physiopathologic and biochemical nature of prostaglandins (PGs) suggest that PGs play a role in reproductive physiology. In vitro studies show that the PGE series decrease the motility of the human uterus, fallopian tubes, and ureter, and produce vasodilatation. PGFs cause vasoconstriction and increased motility of the uterus, fallopian tubes, ureter, and gastrointestinal muscle. PGs are also known to inhibit lipolysis, platelet aggregation, and gastric secretion. The exact mechanism of PGs are not fully understood, but evidence suggests that many responses can be attributed to interference with the enzyme adenyl cyclase, which catalyzes the formation of adenosine 3',5'-monophosphate (cyclic AMP) from adenosine triphosphate. The adenyl cyclase-cyclic AMP system mediates lipolysis, steroidogenesis, gastric secretion, certain smooth muscle motility responses, and increase in permeability due to vasopressin. Early studies of the myometrial effects of PGs showed that the PGE series inhibited the motility of the human myometrium in vitro while the PGF series produced mixed responses. The role of PGF2alpha in parturition has not been established but evidence suggests that it has a potential role as an oxytocic in cases of therapeutic abortion. In the area of human fertility, the physiologic role of PGs in seminal fluid is hypothesized to facilitate the migration of spermatozoa from the vagina into the uterine cavity. Karolinska Institute researchers have found that some infertile males have low PG levels in their ejaculates and are now working with methods of improving the PG levels to improve their fertility. Pickles et al. proposed a potential role for PGs in the etiology of dysmenorrhea, having found a significantly higher ratio of PGF to PGE in a series of patients with severe dysmenorrhea than in a comparable series of normal patients. The luteolytic and antinidatory effects of PGF2alpha are being investigated and studies appear encouraging. PGs have therapeutic potentials in induction of labor, treatment of infertility, morning-after conception, treatment of dysmenorrhea, and contraception by alteration of fallopian tube motility.
