Complete septate uterus with longitudinal vaginal septum.

OBJECTIVE: To review clinical implications, reproductive outcome, and long-term consequences in women with complete septate uterus and longitudinal vaginal septum. DESIGN: A retrospective study. SETTING: A university hospital. PATIENT(S): Sixty-seven patients who had a complete septate uterus including the cervix and a longitudinal vaginal septum. INTERVENTION(S): The longitudinal vaginal septum was incised in 36 cases and metroplasty for uterine septum was undertaken in 4 patients. MAIN OUTCOME MEASURE(S): Fertility, outcome of pregnancies, possible late consequences, and presence of other anomalies. RESULT(S): Eight (15.7%) of 51 women attempting pregnancy had primary infertility of nonuterine causes. Forty-nine women not undergoing metroplasty produced 115 pregnancies, abortion rate 27%, preterm delivery 12%, and live birth rate 72%. Only five women with no metroplasty had only miscarriages and 44 women at least one delivery. One of four women undergoing metroplasty delivered preoperatively and three after metroplasty. During the follow-up period endometriosis was observed in two (3%) of 61 cases and two patients had borderline ovarian tumors. Kidney abnormalities were found in 11 (20%) of 55 patients studied, double ureter being the most common. CONCLUSION(S): Complete septate uterus with longitudinal vaginal septum is not associated with primary infertility, and pregnancy may progress successfully without surgical treatment. The results do not support elective hysteroscopic incision of the septum in asymptomatic patients or before first pregnancy.

Transvaginal myomectomy with screw traction by colpotomy.

INTRODUCTION: The aim of this study is to evaluate the clinical effectiveness and safety of the enucleation of uterine leiomyomas by traction method via colpotomy. METHODS: Ten women with menorrhagia, pelvic pain, or secondary infertility associated with single uterine myomas underwent transvaginal myomectomy with screw traction by colpotomy. The feasibility of the procedure, operative complications, postoperative recovery, pregnancies, and relief of symptoms were the main outcome measures. RESULTS: Traction myomectomy was completed vaginally in all patients. The mean operating time was 71 min and average blood loss 385 ml. The mean size of a single myoma was 6.7 cm (range 5.6-8.0 cm) and weight 153 g. One patient developed a transient hematoma. All women reported relief of their symptoms after a mean follow-up of 24 months. Three patients had a term delivery postoperatively. CONCLUSIONS: Traction myomectomy by colpotomy is a feasible approach for selected patients wishing to preserve their ability to conceive. A single well-lined myoma of 5-8 cm diameter and possible to reach via colpotomy is a suitable subject for the procedure, which proved a viable surgical approach.

Gestational hypertension and preeclampsia associated with unilateral renal agenesis in women with uterine malformations.

OBJECTIVE: To evaluate the possible connection between gestational hypertensive disorder and unilateral renal agenesis in women with congenital uterine anomalies. STUDY DESIGN: Thirty-three (16%) out of 206 women with uterine anomalies had unilateral renal agenesis. Nineteen of them had delivered and comprised the study group. The control group consisted of 44 women among the 206 with similar uterine malformations who had normal bilateral kidneys and matched in age and parity with the study group. Retrospective analysis considered the presence of gestational hypertension, proteinuria, preeclampsia, perinatal outcomes and manifestations of hypertension and renal disease during the follow-up period in both groups. The median follow-up was 166 months (range 24-372 months). RESULTS: Women with unicornuate uterus most frequently (25%) evinced unilateral renal agenesis. Eight (42%) out of 19 women with malformed uterus and unilateral renal agenesis had in at least one pregnancy gestational hypertension, preeclampsia or gestational proteinuria compared to 8 (18%) out of 44 women with two kidneys (relative risk, RR 2.33, 95% CI 1.02, 5.29). Seventeen (35%) out of all 49 pregnancies in the study group were complicated by gestational hypertensive disorder or proteinuria as against 10 (11%) out of 90 pregnancies in the control group (RR 3.12, 95% CI 1.55, 6.28). Perinatal outcomes were similar in both groups. During follow-up none had diagnosed proteinuria or chronic renal disease, but two out of 19 women (11%) with unilateral renal agenesis had commenced medication for chronic hypertension. CONCLUSION: Unilateral renal agenesis predisposes women with uterine anomalies to preeclampsia.

Fatty acid and cholesterol composition of the uterine artery intima in relation to menopausal status, age, and serum cholesterol.

OBJECTIVES: Estrogens modulate lipid metabolism and the increased risk of atherosclerosis in postmenopausal women is at least partly due to the reduction of estrogen production after menopause. We studied the effect of menopause on the contents of long-chain fatty acids, free cholesterol (FC) and cholesterol ester (CE) in uterine artery wall. METHODS: The uterine artery intima samples were obtained in connection with surgery of 21 postmenopausal and 51 premenopausal women. The amount of FC, CE and phospholipid fatty acids were measured by gas chromatography after extraction and fractionation and these lipid values were related to menopausal status, age and serum total and low-density lipoprotein (LDL) cholesterol levels. RESULTS: Premenopausal females had significantly less intimal FC (161 +/- 50 vs. 407 +/- 276 microg/100 mg wet weight, P = 0.003) and CE (19 +/- 34 vs. 305 +/- 348 microg/100 mg wet weight, P = 0.050) and smaller proportion of linoleic acid out of all phospholipid fatty acids (4.2 vs. 7.2%, P = 0.002) than postmenopausal women after adjustment with age. The content of CE (r = 0.34, P = 0.025) and the FC-to-CE ratio (r = -0.45, P = 0.002) correlated with age in premenopausal but not in postmenopausal women. Moreover, the intimal content of CE correlated with the percentage of intimal phospholipid linoleic acid in postmenopausal women (r = 0.79, P = 0.020). The same was true for FC (r = 0.73, P < 0.001). CONCLUSIONS: These results indicate that CE and FC accumulation into the wall of uterine artery depends on menopausal status, independently of age, and that the phospholipid long-chain fatty acid composition differs significantly between premenopausal and postmenopausal women. This suggests that estrogens may be involved in the regulation of artery wall lipid composition.

Transanal or vaginal approach to rectocele repair: a prospective, randomized pilot study.

PURPOSE: This study was designed to compare outcomes of transanal and vaginal techniques for rectocele repair. METHODS: Thirty females with symptomatic rectocele were enrolled in a prospective, randomized study. Fifteen underwent transanal rectoceleplasty, the other 15 underwent vaginal posterior colporrhaphy. Patients were assessed by clinical interview and examination, defecography, colon transit study, and anorectal manometry before randomization and 12 months postoperatively. Patients with compromised anal sphincter function or other symptomatic prolapse were excluded. RESULTS: The study groups were comparable in terms of demographic factors and rectocelerelated symptoms and signs. Eleven (73 percent) patients in the vaginal group and 10 (66 percent) in the transanal group digitally assisted rectal emptying preoperatively. The mean depth of the rectocele was 6.0 +/- 1.6 cm vs. 5.6 +/- 1.8 cm (P = 0.53) in the respective groups. At follow-up, 14 (93 percent) patients in the vaginal group and 11 (73 percent) in the transanal group reported improvement in symptoms (P = 0.08). Need to digitally assist rectal emptying decreased significantly in both groups, to one (7 percent) for the vaginal group and four (27 percent) for the transanal group (P = 0.17 between groups). The respective recurrence rates of rectocele were one (7 percent) vs. six (40 percent) (P = 0.04), and enterocele rates were zero vs. four (P = 0.05). In the vaginal group defecography showed a significant decrease in rectocele depth whereas in the transanal group the difference did not reach statistical significance. None of the patients reported de novo dyspareunia, but 27 percent reported improvement. CONCLUSION: Patients' symptoms were significantly alleviated by both operative techniques. The transanal technique was associated with more clinically diagnosed recurrences of rectocele and/or enterocele. Adverse effects on sexual life were avoided by use of both techniques.

Expression of nuclear receptors and cofactors in human endometrium and myometrium.

OBJECTIVE: To study the expression of nuclear receptors and cofactors in human endometrium and myometrium in proliferative and secretory phases of the menstrual cycle. METHODS: Multiprobe ribonuclease protection assay and real-time reverse transcriptase polymerase chain reaction were used to quantitate mRNA levels of steroid receptors, vitamin D receptor (VDR), retinoic acid receptors (RAR), and cofactors AIB1 (amplified in breast cancer-1), CBP (cyclic adenosine monophosphate response element binding protein), pCAF (p300/CBP-associated factor), TIF2 (transcription intermediary factor-2), N-CoR (nuclear receptor corepressor), and SMRT (silencing mediator of repressed transcription). Cyclin A expression was analyzed to determine the proliferation status of the tissues. RESULTS: The expression of androgen receptor, estrogen receptors alpha and beta, progesterone receptor, and RARalpha followed cyclin A expression. There was more abundant expression in the proliferative phase endometrium than in the secretory phase endometrium. Glucocorticoid receptor, VDR, RARbeta, and RARgamma were stably expressed during the menstrual cycle in both endometrium and myometrium. Cofactors N-CoR, SMRT, pCAF, CBP, TIF2, AIB1, and p300 mRNAs were expressed in all samples in both endometrium and myometrium. N-CoR, pCAF, AIB1, and p300 appeared not to be regulated when comparing proliferative and secretory phases of the cycle. Individual differences were found in the expression levels of both nuclear receptors and cofactors. CONCLUSION: The menstrual cycle-dependent regulation of nuclear receptor expression was more apparent in the endometrium than in the myometrium, whereas cofactor expression was not cycle dependent. There were individual differences in the expression levels of different receptors and cofactors. In hormonal therapy these differences might result in different responses, depending on the patient as well as the ligand used.

Clinical outcome and complications of laparoscopic surgery compared with traditional surgery in women with endometrial cancer.

INTRODUCTION: The purpose of this study was to evaluate the feasibility, clinical outcome and complications of laparoscopic surgery in women with endometrial cancer and to compare surgical outcome and postoperative early and late complications with results of traditional laparotomy. METHODS: Forty women with endometrial cancer underwent laparoscopic hysterectomy, bilateral salpingo-oophorectomy and pelvic lymphadenectomy. Each patient operated by laparoscopy was matched by age, preoperative clinical stage and histology of the endometrial cancer with a patient treated by the same operation but using traditional laparotomy. Half of these patients underwent total pelvic lymphadenectomy and half had pelvic lymph node sampling. The groups were compared in clinical characteristics, surgical outcomes, recoveries and early and late postoperative complications. RESULTS: The patients in the laparoscopy group had less blood loss, more lymph nodes removed, shorter hospital stay but longer operation time than those treated by laparotomy. Only one (2.5%) laparoscopy was converted to laparotomy due to pelvic adhesions. There were no intraoperative complications in either group. Postoperative complications were more common (55.0%) in the laparotomy than in the laparoscopy group (37.5%). Only one major complication (2.5%) occurred among patients undergoing laparoscopy as compared with three (7.5%) major complications in the laparotomy group. Superficial wound infection was the most common (20%) infection in laparotomy patients while vaginal cuff cellulitis occurred in 10% of laparoscopy patients. Late (>42 days) postoperative complications were almost equally frequent (20.0 and 22.5%) in both groups. Lower extremity lymph edema or pelvic lymph cyst was found in 12.5% of all cases. As a result of surgical staging the disease of 6 women (15%) in both groups was upgraded. CONCLUSIONS: Laparoscopic surgery is a viable alternative to traditional surgery in the management of endometrial cancer. The surgical outcome is similar in both cases. In laparoscopic procedures the operation time is longer but the postoperative recovery time shorter than in laparotomy. Severe complications were limited in both groups, while wound infections can be avoided using laparoscopy.

Presenting and long-term clinical implications and fecundity in females with obstructing vaginal malformations.

OBJECTIVE: To evaluate presenting and long-term clinical consequences in females with obstructing vaginal anomalies. DESIGN: A retrospective study. SETTING: A university hospital in southern Finland. PARTICIPANTS: Twenty-six females with obstructing vaginal malformations. The conditions were classified into transverse vaginal obstruction (transverse septum or imperforate hymen) and longitudinal vaginal obstruction (longitudinal vaginal septum). INTERVENTIOS: 13 out of 16 women with transverse vaginal obstruction underwent incision of the imperforate hymen and three underwent excision of a complete transverse vaginal septum. Ten patients with obstructing hemivagina had incision of the longitudinal vaginal septum. MAIN OUTCOME MEASURES: Presenting symptoms and delay in diagnosis, outcome of primary surgical treatment, possible late complaints associated with obstruction, fecundity, perinatal outcome, and presence of other anomalies were studied. The mean followup period in the transverse and longitudinal obstruction group respectively was 13 years (range 1-29) and 16 years (range 1-44). RESULTS: Transverse vaginal obstructions were diagnosed within less than a month from the primary symptoms, while the diagnosis of longitudinal obstruction was delayed for an average of 27 months. Two out of three females with transverse vaginal septum underwent re-operation for vaginal constriction and three out of 10 with longitudinal vaginal septum had re-excision of the septum. All females with longitudinal obstruction had uterine and renal malformations as opposed to those with transverse vaginal obstruction. In the transverse vaginal obstruction group, two out of the six females who had their renal status assessed had double ureters. Dysfunctional uterine bleeding (19% in the transverse and 40% in the longitudinal obstruction group), dyspareunia (30% and 0%) and dysmenorrhea (19% and 20%) were the most common complaints during the followup. No endometriosis was found in the group that underwent a subsequent laparotomy or laparoscopy (18/26). Female infertility was not found in those 14 females who were attempting to conceive. Twenty-five (89%) out of 28 pregnancies ended in delivery, the live birth rate being 82% in the longitudinal and 94% in the transverse obstruction group. CONCLUSION: Accurate diagnosis together with adequate treatment may reduce the need for re-operations in cases with obstructing vaginal malformations. No specific gynecologic long-term clinical symptoms were identified in obstructing vaginal anomalies.

Anatomic and functional assessment and risk factors of recurrent prolapse after vaginal sacrospinous fixation.

BACKGROUND: To identify risk factors in recurrence and to evaluate anatomic and functional results of vaginal sacrospinous ligament fixation and pelvic floor reconstruction for genital prolapse. METHODS: One hundred and thirty-eight women underwent surgery for uterovaginal or vault prolapse. Follow-up data were available for 122 cases; 83% were examined and others were interviewed by telephone. The median (range) follow-up was 24 (1-141) months. Cox regression was used to identify risk factors associated with recurrence; uni- and multivariate regression was used to identify risk factors underlying postoperative infections because infections were found to be a risk factor of recurrence. Recurrence-free survival was estimated using the Kaplan-Meier method. RESULTS: Seven (5%) patients suffered severe cardiopulmonary complications including one postoperative death due to a pulmonary embolism. Twenty-six (21%) patients suffered a recurrence, 14 with cystocele. Ten patients with recurrence were symptomatic and six underwent a re-operation. The Cox regression model showed that vaginal cuff infection raised the odds ratio (OR) for recurrence to 6.13 [confidence interval (CI) 1.80-20.83] and urinary tract infection to 3.65 (CI 1.40-9.47). In both uni- and multivariate analysis, lack of intravenous antibiotic prophylaxis, age less than 73 years and vaginal ulcerations were statistically significant risk factors for postoperative infection. Eleven (33%) out of 33 sexually active women reported improvement and three (9%) complained of dyspareunia. CONCLUSIONS: Transvaginal sacrospinous ligament fixation with pelvic floor repair is an effective means of correcting both vault prolapse and uterine procidentia. Women who wish to preserve coital function will also benefit from this operation. Postoperative infection is an independent and most important individual risk factor underlying recurrence. Prophylactic antibiotics seem to be effective in reducing the rate of postoperative infections.

Fecundity and morbidity following acute pelvic inflammatory disease treated with doxycycline and metronidazole.

We studied fecundity and late sequelae of 39 women who had laparoscopic and microbiological sampling-proven acute pelvic inflammatory disease (PID) treated with the same antimicrobial regimen. The grade and etiology of index PID were classified using laparoscopy, endometrial biopsy and microbiological cultures from the cervix, endometrium and tubes: 20 had mild and 19 severe PID. The mean (SD) follow-up period after the index PID was 125 (44) [range 8-204] months. The primary end-point was pregnancy. All other or recurrent infections or other diseases related to the infection, including infertility, were evaluated. Twenty (51%) women had laparotomy or second laparoscopy during follow-up and findings were evaluated. Chlamydia trachomatis was isolated in 38% of all cases. Eleven (28%) of 39 women avoided conception or it was no longer possible. Twenty-eight women had tried to conceive after the index PID and 25 (89%) of them had at least one pregnancy. Twenty-five women had 56 pregnancies, 33 (59%) of which ended in delivery, 9 (16%) miscarried, 13 (23%) were induced abortion and only one (1.8%) tubal pregnancy occurred. Etiologic factors or severity of PID made no difference to the conception rate. Patients with mild or moderate salpingitis had a high conception rate. Endometriosis was found in 6 (30%) out of 20 women with second laparoscopy or laparotomy. Hysterectomy had been performed in 4 cases. Precise diagnosis of acute PID is the cornerstone for the treatment of the condition. Combination regimens, including drugs against the most common factors underlying acute PID against both aerobic and anaerobic microbes, prevent late sequelae in cases with mild or moderate salpingitis but not in cases with tubal or pelvic abscess.

Gonadoblastoma and dysgerminoma associated with XY gonadal dysgenesis in an adolescent with chronic renal failure: a case of Frasier syndrome.

STUDY OBJECTIVES: To report a rare reason for primary amenorrhea, a Frasier syndrome, XY gonadal dysgenesis associated with renal failure with eventual development of gonadoblastoma. To study immunohistochemical analysis of gonadoblastoma and dysgerminoma. To analyze the possibility of androgen receptor mutation in this rare syndrome. METHODS: We report a case of a 16-yr-old female with this syndrome. She underwent a laparoscopic bilateral gonadectomy and salpingectomy. A histopathological examination revealed gonadoblastoma with focal malignant dysgerminoma in the left dysgenetic gonad and an immunohistochemical of these fairly rare, malignant tumors. An androgen receptor was coded. Analysis was done. RESULTS: Immunohistochemical analysis showed that inhibin was strongly positive in gonadoblastoma but negative in dysgerminoma. No mutations of the androgen receptor gene were found. CONCLUSIONS: Inhibin positivity in gonadal stroma and in gonadoblastoma may indicate hormonal activity causing advanced puberty in patients with XY gonadal dysgenesis.

Ovarian manifestations in women with autosomal dominant polycystic kidney disease.

BACKGROUND: Ovarian cysts are found in some premenopausal women with autosomal dominant polycystic kidney disease (ADPKD). Liver cysts are the major extrarenal manifestations, frequently found in postmenopausal women. Female steroid hormones may regulate hepatic cystogenesis, but ovarian manifestations in postmenopausal women are unknown. The aim of the present study is to investigate possible ovarian manifestations associated with ADPKD in premenopausal and postmenopausal women. METHODS: The study group included 19 premenopausal or postmenopausal women with ADPKD and 19 age- and parity-matched control women with no history of renal disease. Ovarian structures and volumes were measured by means of transvaginal ultrasonography. RESULTS: Three of 8 premenopausal and 1 of 11 postmenopausal women with ADPKD had a small unilateral single ovarian cyst; there were none in controls. Eight women with ADPKD and 8 controls of premenopausal age had similar ovarian volumes (4.92 +/- 2.97 versus 3.92 +/- 2.60 cm3). Eleven postmenopausal women with ADPKD had an increased mean ovarian volume compared with 11 postmenopausal controls (4.11 +/- 2.60 versus 1.66 +/- 0.96 cm3; P < 0.01). Ovarian volume was not associated with the use of hormonal replacement therapy or impaired renal function in postmenopausal women with ADPKD. CONCLUSION: ADPKD is not associated with cystic ovaries, although single ovarian cysts are occasionally found. Equal ovarian volumes between premenopausal and postmenopausal women with ADPKD suggest a possible indirect effect of polycystic kidneys on gonads in aging women.
