RESUMO

ObjectivesWe aimed to examine the change in plasma copper (Cu) level and copper transport proteins level before inserting Cu-IUD and after one menstrual cycle and to show the effect of this change on the thiol disulfide balance in women using copper-containing intrauterine device (Cu-IUD).MethodThirty-three reproductive women who admitted to the gynecology clinic and inserted Cu-IUD were examined in this study. Thiol-disulfide homeostasis, plasma Cu and ceruloplasmin levels and ceruloplasmin ferroxidase activity were measured using the blood samples collected just before inserting Cu-IUD and after one menstrual cycle.ResultsPlasma copper level (p = 0.006), ceruloplasmin (p < 0.001), Ceruloplasmin Ferroxidase (p = 0.005), thiol disulfide homeostasis parameters; native thiol (NT) (p = 0.004), and total thiol (p = 0.003) levels increased significantly.ConclusionAfter one menstrual cycle in women inserted intrauterine Cu-IUD for contraception, plasma levels of Cu, which is the oxidant molecule, increased significantly. Both plasma ceruloplasmin level and ceruloplasmin ferroxidase activity increased due to elevated Cu levels. This increased oxidant status in the acute period was balanced by the increase in the native thiol level.

RESUMO

Laminin receptor 1 may have a role in the progression from endometrial hyperplasia with or without atypia to endometrial cancer. Therefore, we aimed to investigate the pattern, percentage, and intensity of laminin receptor 1 expression in normal, hyperplastic, and neoplastic endometrium. Paraffin blocks of 131 specimens with the diagnoses of normal endometrium (n=25), endometrial hyperplasia with atypia (n=21) or without atypia (n=55), and endometrial cancer (n=30) were immunostained with laminin receptor 1 antibody, and its expression percentage, pattern, and intensity in the epithelial cytoplasm, basement membrane, and endometrial stroma of these tissues were assessed. When compared with hyperplasia with or without atypia and endometrial cancer, the percentage of nonstaining with laminin receptor 1 in the epithelial basement membrane was higher (96%), and the percentage of <50% staining with laminin receptor 1 was lower (4%) in the normal endometrium (P=0.001). While a progressive increment in staining percentage and density of epithelial cytoplasm and basement membrane was noted through an orderly progression from normal endometrium to endometrial hyperplasia without atypia, endometrial hyperplasia with atypia, and cancer of endometrium (P<0.001), such a relationship was not found for the staining percentage and density of endometrial stroma (P>0.05). Disease progression-related gradual increment in laminin receptor 1 expression in the epithelial basement membranes of hyperplastic endometrium with or without atypia and cancer of endometrium reveals that it may play a substantial role in the transition from premalignant to the malignant state of endometrial lesions.

RESUMO

AIM: To compare maternal, fetal and placental trace element (magnesium, zinc and copper) and heavy metal (cadmium and lead) and maternal vitamin (retinol, α [alpha]-tocopherol, vitamin D3 , 25-hydroxyvitamin D3 and 1,25-dihydroxyvitamin D3 ) levels in preterm deliveries with and without preterm premature rupture of membranes (PPROM). METHODS: Sixty-eight patients giving birth preterm were grouped into preterm deliveries with PPROM (n = 35) and without PPROM (n = 33). Following delivery, maternal and umbilical cord blood sera and placental tissue samples were obtained. While magnesium, zinc, copper, cadmium and lead levels were measured in all samples, the levels of retinol, α-tocopherol, vitamin D3 , 25-hydroxyvitamin D3 and 1,25-dihydroxyvitamin D3 were measured only in maternal serum. RESULTS: While magnesium level in maternal serum and zinc levels in both maternal and umbilical cord sera were lower, placental magnesium level was higher in preterm deliveries with PPROM (P < 0.01). Umbilical cord serum magnesium, placental tissue zinc and maternal and umbilical cord sera and placental tissue copper, cadmium, and lead levels did not differ between the groups (P > 0.05). In preterm deliveries with PPROM, 25-hydroxyvitamin D3 and retinol levels were higher, while vitamin D3 and 1,25-dihydroxyvitamin D3 levels were lower in maternal serum (P < 0.05). Maternal serum α-tocopherol levels were similar between the groups. CONCLUSION: Compared to spontaneous preterm births, PPROM is associated with low maternal serum together with high placental tissue magnesium and low maternal and umbilical cord sera zinc levels. Higher retinol and 25-hydroxyvitamin D3 and lower vitamin D3 and 1,25-dihydroxyvitamin D3 maternal serum levels are also evident in these patients.

RESUMO

BACKGROUND: To evaluate amniotic fluid pro- and anti-inflammatory cytokine levels in women with postterm and term pregnancies in labor and not in labor. METHODS: The study involved three groups: postterm (Group 1, n = 29), term in labor (Group 2, n = 28), and control (Group 3, n = 30). All groups were compared with respect to age, gravidity, parity, obstetric history, gestation week, cervical dilatation and effacement, maternal serum C-reactive protein and white cell count, amniotic interleukin 4, 6, and 10 levels, birthweight, and cord blood pH. RESULTS: The amniotic fluid interleukin 10 level was 24.4 ± 8.8 pg/mL in the postterm group, 13.5 ± 5.1 pg/mL in the term in labor group, and 19.8 ± 5.4 pg/mL in the control group (p < 0.001). The amniotic fluid interleukin 4 level was 86.5 ± 57.7 pg/mL in the postterm group, 38.2 ± 29.2 pg/mL in the term in labor group, and 81.9 ± 68.4 pg/mL in the control group (p = 0.002). The amniotic fluid interleukin 6 level was 329 ± 135.1 pg/mL in the postterm group, 252.8 ± 138.7 pg/mL in the term in labor group, and 227.9 ± 114.4 pg/mL in the control group (p = 0.02). There was a positive correlation between gestational age and IL-10 levels (p < 0.05). CONCLUSIONS: Amniotic fluid IL-10 and IL-4 cytokine levels were increased in postterm pregnancy and they decreased with active labor.

RESUMO

The aims of this prospective study were to detect maternal serum chemerin level in patients with preeclampsia and investigate its association with disease severity and neonatal outcomes. Maternal serum chemerin levels were significantly elevated in severe preeclamptic women (394.72 ± 100.01 ng/ml) compared to mild preeclamptic women (322.11 ± 37.60 ng/ml) and healthy pregnant women (199.96 ± 28.05 ng/ml) (p = .001). Maternal serum chemerin levels were positively correlated with systolic and diastolic blood pressure, C-reactive protein levels, homeostasis model assessment of insulin resistance, proteinuria, AST, ALT, and duration of hospitalisation. Gestational week at delivery, birthweight, and APGAR scores at 1 and 5 min were negatively correlated with maternal serum chemerin level. A maternal serum chemerin level of >252.0 ng/ml indicated preeclampsia with 95.5% sensitivity and 95.7% specificity. There was a positive correlation between maternal serum chemerin level and severity of preeclampsia. Additionally, adverse neonatal outcomes were significantly associated with high maternal serum chemerin levels.

RESUMO

BACKGROUND The purpose of our study was to investigate the association between polycystic ovary syndrome (PCOS) and hearing thresholds. MATERIAL AND METHODS Forty women diagnosed with PCOS (mean age, 24.33±6.38 years) and 40 healthy women controls (mean age, 26.38±6.75 years) were included in prospective study. Each case was tested with low (250, 500, 1000, and 2000 Hz), high (4000, 6000, and 8000 Hz) and extended high (EH) (9000-20000 Hz) frequency audiometry. The fasting plasma glucose, insulin, FSH, LH, total testosterone, and sex hormone-binding globulin were measured in all patients. RESULTS The mean hearing thresholds at EH frequencies were statistically significantly higher in the PCOS group than in the control group (p=0.001 right ear and p=0.015 left ear). There were significant positive correlations among free testosterone index (FTI) values and hirsutism scores with EH frequency hearing thresholds. CONCLUSIONS At pure-tone audiometry (PTA) EH frequencies, we detected significantly higher hearing thresholds in PCOS patients than in controls. We also determined that elevated FTI and hirsutism score were positively correlated with elevated hearing thresholds in EH frequencies. These findings support that hyperandrogenism can play a role in the elevation of hearing thresholds in PCOS.

RESUMO

Sarcomas of the vulva in the Bartholin's gland area are extremely rare in adults and only a few cases have been reported in the literature. A 65-year-old female patient without any previous complaint presented to our hospital complaining of a genital lump with progressive enlargement over the last six months. Pelvic examination revealed a 6 × 5 cm solid mass lesion with irregular margins localized in the left Bartholin's gland. Preoperative pathology results indicated a benign lesion, which was subsequently totally excised. Histopathological examination of the lesion revealed leiomyosarcoma. When a lesion is localized in the Bartholin's gland area, preoperative biopsy may suggest benign cytology, which can lead to a delay in diagnosis and curative treatment. Total local excision is the first choice for vulvar-complicated masses in the Bartholin's gland area. The present case is the ninth well-documented case reported in the literature.

RESUMO

PURPOSE: To compare the clinical and perinatal outcomes in eclamptic women with and without posterior reversible encephalopathy syndrome (PRES). METHODS: This single-center, retrospective, cohort study was conducted between 2008 and 2013. The clinical and perinatal outcomes of eclamptic patients were obtained from hospital records. Magnetic resonance imaging was used for the diagnosis of PRES. Eighty-one eclamptic women were divided into two groups: 45 and 36 patients were included in the PRES and non-PRES groups, respectively. RESULTS: In the PRES group, headache and visual impairment together (60.0 %) were the most common presenting symptoms. In the non-PRES group, only headache was the most common (50 %) presenting symptom. Occipital and parietal lobes were the most frequently affected areas in the PRES group. Women in the PRES group had a higher body mass index value (p = 0.005), longer hospitalization time (p = 0.001), and higher level of proteinuria (p = 0.012) than those in the non-PRES group. Women in the non-PRES group had higher Apgar scores (p = 0.002) than those in the PRES group. CONCLUSIONS: This study indicates that PRES manifests predominantly with headache and visual impairment together. Adverse neonatal outcomes are also common in these patients.

RESUMO

Laminin receptor 1 (LAMR) may have a role in the progression of premalignant squamous epithelial lesions to cervical cancer. Therefore, we aimed to investigate the expression of laminin receptor 1 (LAMR) in normal, premalignant, and malignant tissues of the uterine cervix. Paraffin blocks of 129 specimens with the diagnoses of normal cervical tissue (n = 33), cervical intraepithelial neoplasia (CIN) 1 (n = 30), CIN 2 (n = 14), CIN 3 (n = 28), and squamous cell carcinoma (n = 24) were immunohistochemically stained with LAMR antibody and its expression percentage, pattern, and intensity in these tissues were assessed. Compared to the other groups, the nonstaining with LAMR was highest in low grade squamous intraepithelial lesion (LSIL) (p < 0.0001). LAMR expression, which was positive in less than 50% of cells with weak staining, increased significantly between normal cervical epithelium and high-grade squamous intraepithelial lesion (HSIL) or invasive carcinoma, as well as between LSIL and HSIL (p < 0.0001). Between LSIL and invasive carcinoma, a significant increment was also observed for weak staining in less than 50% of cells (p < 0.001). LAMR expression, which was positive in more than 50% of cells with strong staining, was significantly higher in normal cervical tissue compared to the other groups (p < 0.0001). Disease progression related gradual increment of LAMR expression from normal cervical epithelium or LSIL towards HSIL or cervical cancer reveals that LAMR may play an important role in the transition from premalignant to malignant state in cervical lesions.

RESUMO

OBJECTIVE: To evaluate serum myeloperoxidase (MPO) and adenosine deaminase activities and to investigate whether there was a correlation between these and sex hormones, and lipids in polycystic ovary syndrome. DESIGN AND METHODS: Forty-five women with polycystic ovary syndrome and 40 healthy controls were included in this study. Leukocyte counts, serum MPO and adenosine deaminase activities, and high-sensitive C-reactive protein (hs-CRP), sex hormone and lipid levels were assessed. RESULTS: Leukocyte counts and serum MPO activities were higher (p < 0.01 and p < 0.05, respectively) and there was a significant correlation between serum adenosine deaminase and hs-CRP level in women with polycystic ovary syndrome (r = 0.853, p < 0.01). Serum MPO and adenosine deaminase levels did not correlate with sex hormones or lipid profiles in these patients. CONCLUSION: Polycystic ovary syndrome may involve an inflammatory process by increasing serum MPO activity independent of sex hormones, body mass index and lipid profiles.

RESUMO

OBJECTIVES: To evaluate sexual function and psychological state and the factors affecting female sexual dysfunction in predialysis and hemodialysis patients. DESIGN AND METHODS: Forty-seven women with chronic renal failure including 22 predialysis patients, 25 hemodialysis patients, and 30 healthy controls were included in this study. Demographic and clinical variables of the patients were recorded. The sexual functions and psychological states of the patients, assessed by the Arizona Sexual Experiences Scale (ASEX) and Beck Depression Inventory (BDI), respectively, were compared between the groups. RESULTS: Total ASEX scores, ability to reach orgasm, and BDI scores were significantly higher in predialysis and hemodialysis patients than controls, reflecting sexual dysfunction. The patients in the predialysis group were 6 and 3.8 times more likely to develop depressive symptoms compared to the controls and hemodialysis patients, respectively. The predialysis patients who showed depressive symptoms were 24 times more likely to develop sexual dysfunction compared to those without depression. Serum FSH and LH levels were also positively correlated with arousal and erection/lubrication scores in the predialysis patients with depressive symptoms. CONCLUSION: Female predialysis rather than dialysis patients might be more likely to develop depression. Those patients with depressive symptoms may also be at greater risk of developing sexual dysfunction in which increased gonadotropin levels and age may also be contributing factors. Therefore, psychiatric and gynecologic consultations may be beneficial.

RESUMO

We aimed to evaluate whole blood adenosine deaminase (ADA), myeloperoxidase (MPO), butyrylcholinesterase (BChE), and acetylcholinesterase (AChE) activities and to investigate whether there was a correlation between these enzymes and severity of preeclampsia and neonatal outcomes. Sixty-one pregnant women with mild (n = 31) or severe (n = 30) preeclampsia and 50 healthy controls were included in this study. Whole blood adenosine deaminase, myeloperoxidase, butyrylcholinesterase, and acetylcholinesterase activities were measured. Adenosine deaminase and myeloperoxidase activities were significantly higher in both mild and severe preeclamptic women than they were in the controls. There was also a significant difference between the severe and the mild preeclamptic groups with respect to these enzyme activities. Although BChE activity was lower in the severe preeclamptic women than it was in the healthy controls (P < .05), AChE activity was similar in all groups (P > .05). We noted an inverse correlation between ADA activity and birth weight (r = -0.337) (P < .05) and between MPO activity and Apgar scores at 1 and 5 minutes (r = -0.438 and r = -0.475, respectively, P < .01). We concluded that elevated ADA and MPO but not AChE activities may correlate with disease severity and neonatal outcomes in preeclamptic women. Further studies are needed to elucidate the exact roles of ADA and MPO in the pathophysiology of preeclampsia.

RESUMO

OBJECTIVE: To investigate the effect of intranasal estrogen replacement therapy administered to postmenopausal women alone or in combination with progesterone on markers of cardiovascular risk. METHODS: The study was conducted with 44 voluntary postmenopausal women. In group I (n = 15), the patients were treated with only intranasal estradiol (300 µg/day estradiol hemihydrate). In group II (n = 11), the patients received cyclic progesterone (200 mg/day micronized progesterone) for 12 days in each cycle in addition to continuous intranasal estradiol. Group III (n = 18) was the controls. Serum lipid profiles, oxidised low-density lipoprotein (LDL) and other markers of cardiovascular risk were assessed at baseline and at the 3rd month of the treatment. RESULTS: Lipid profile, LDL apolipoprotein B, lipoprotein a, homocysteine, oxidised LDL values and oxidised LDL/LDL cholesterol ratio were not observed to change after 3 months compared to baseline values within each group (p > 0.016). In comparison to changes between the groups after the treatment, only oxidised LDL levels and oxidised LDL/LDL cholesterol ratios of group II were increased compared to control group (p < 0.05). CONCLUSIONS: Intranasal estradiol alone did not appear to have an effect on markers of cardiovascular risk in healthy postmenopausal women. However, the addition of cyclic oral micronized progesterone to intranasal estradiol influenced the markers of cardiovascular risk negatively in comparison to non-users in healthy postmenopausal women.

RESUMO

OBJECTIVES: To investigate the expression of laminin receptor 1 (LR1), a non-integrin-type laminin receptor, in preeclamptic and normal third-trimester placentas, as well as to investigate whether its expression differs with disease severity. STUDY DESIGN: Third trimester placental samples obtained from deliveries of preeclamptic (n=34) and normotensive healthy pregnant women (n=35) were immunohistochemically studied for the expression of LR1. The placentas from both mild (n=14) and severe (n=20) preeclamptic pregnancies were further assessed for strength of LR1 expression according to disease severity. RESULTS: When compared with normal placentas, the staining with LR1 protein in cytotrophoblasts and syncytiotrophoblasts was lower in preeclamptic placentas (P<0.05 and P<0.01, respectively). The intensity of staining with LR1 in decidual cells, cytotrophoblasts, syncytiotrophoblasts, and extracellular matrix cells of preeclamptic placentas did not vary with disease severity (P>0.05). CONCLUSIONS: Decreased LR1 expression in cytotrophoblasts and syncytiotrophoblasts of preeclamptic placentas, which may be independent of disease severity, might have a role in shallow trophoblastic invasion in preeclampsia.

RESUMO

PURPOSE: We report the successful management of a pregnancy with preexisting nephrotic syndrome due to biopsy-proven primary membranoproliferative glomerulonephritis type I. METHODS: A 21-year-old Turkish woman with membranoproliferative glomerulonephritis type I was followed up by the obstetrics and gynecology, and nephrology departments of a university hospital throughout her pregnancy starting from the 25th week of gestation. RESULTS: Due to progression of intrauterine growth retardation and fetal distress, a cesarean section was performed in the 33rd week of gestation. Although creatinine was unchanged, proteinuria increased with relatively stable albumin levels 3 months after delivery and her treatment was adjusted accordingly. CONCLUSIONS: If the mother is not suffering from hypertension or renal insufficiency, specific therapy for membranoproliferative glomerulonephritis type I during pregnancy provided by a nephrologist together with regular obstetric care may allow the patient to have a viable fetus, which might be growth retarded if proteinuria is increased.

RESUMO

OBJECTIVE: To review our experience with preterm premature rupture of membranes at a tertiary-care hospital in Turkey to determine whether the amount of residual amniotic fluid after rupture has prognostic value for adverse maternal and fetal outcomes. METHODS: We reviewed the medical records of 191 pregnant women with gestational ages between 24 and 34 weeks at the time of rupture of the amniotic membrane and of their babies delivered in our hospital between January 1996 and September 2008. On the basis of amniotic fluid index (AFI) values recorded at the time of admission, patients were categorized into two groups: those with an AFI < 50 mm (n = 119) and those with an AFI > 50 mm (n = 72). RESULTS: The patients with high gravidity (4-8) were more prevalent in the group with an AFI < 50 mm (37 vs. 23.6%), while nulliparous women were more common in the group with an AFI > 50 mm (44.4 vs. 30.2%) (P < 0.05). Seventy-two percent of the cesarean sections performed due to nonreassuring fetal status were in the group with an AFI < 50 mm (P < 0.01). In 71.4% of the cases with a 5 min Apgar score < or = 7, AFI was less than 50 mm (P < 0.01). AFI < 50 mm was present in 65, 70.8, 76.7, and 73.1% of the pregnancies complicated by chorioamnionitis, respiratory distress syndrome, composite neonatal morbidity, and neonatal death, respectively (P < 0.05). CONCLUSIONS: A residual AFI < 50 mm after preterm PROM between 24 and 34 weeks of gestation, which is mostly seen in grand multiparous women in Eastern Turkey, may be a valuable prognostic variable for anticipating adverse maternal and neonatal outcomes.

RESUMO

AIM: To review our experience with brucellosis in pregnancy and to characterize the risk factors, clinical presentations, the rates of possible perinatal complications, and the effect of hospitalization on pregnancy outcomes. METHODS: We reviewed the medical records of 21 pregnant women at a tertiary care hospital and 12 at a maternity hospital, who presented with acute, subacute, chronic, or relapsing brucellosis. Their risk factors and clinical presentations were defined. The reproductive outcomes of 29 cases were compared within themselves according to the hospitals they were managed and with the outcomes for all women followed in the maternity hospital for the period from January 2008 through December 2008. RESULTS: Consumption of unpasteurized dairy products had occurred in 92.3% of the cases. Spontaneous abortion, intrauterine fetal death, and preterm delivery rates were 24.14, 3.45, and 6.9%, respectively. Only spontaneous abortion rate substantially exceeded that among the general population of pregnant women in our maternity hospital (P<0.05). Hospitalization did not affect pregnancy outcomes significantly (P>0.05). CONCLUSIONS: Brucellosis in pregnancy is associated with increased incidence of spontaneous abortion without an association with the magnitude of serum agglutination titer, the clinical type of brucellosis and hospitalization. In endemic areas with inhabitants of low socioeconomic class and low educational level, educating women of childbearing age about brucellosis may help to prevent the disease and its complications in pregnancy.

RESUMO

OBJECTIVES: To investigate the expression of laminin receptor 1 (LR1), a non-integrin-type laminin receptor, in gestational trophoblastic diseases and normal first-trimester placenta, since it may play a role in controlling trophoblast invasion in normal and molar pregnancies. METHODS: Paraffin sections from 24 gestational age controlled normal first-trimester placentas, 47 partial moles, 56 complete moles, 3 invasive moles, 4 gestational choriocarcinomas, and 1 placental-site trophoblastic tumor were studied immunohistochemically for expression of LR1. RESULTS: In complete and partial moles, decidual cells showed significantly stronger LR1 protein staining compared to the normal placenta (p<0.01). When compared to the partial moles, weak staining in less than 33% of decidual cells was also more prominent in the normal placenta (p<0.05). Complete and partial moles, invasive moles, choriocarcinomas, and placental-site tumors did not differ from each other with respect to staining intensity. Strong immunostaining for LR1 in decidual cells, cytotrophoblasts, syncytiotrophoblasts, and extracellular matrix cells of partial and complete moles was not significantly correlated with the development of persistent postmolar gestational trophoblastic tumors. CONCLUSIONS: LR1 may be important in the pathogenesis of gestational trophoblastic diseases. The increased expression of LR1 in decidual cells of partial and complete moles may not influence the development of persistent gestational trophoblastic tumor. Since they are seen rarely, multicentric studies should be planned to study LR1 expression in invasive moles and gestational trophoblastic neoplasms.

RESUMO

OBJECTIVE: This study presents short-term outcomes related to changes in existing and de novo lower urinary tract symptoms (LUTS), pelvic pain, and bowel function following robot-assisted laparoscopic uterosacral ligament suspension (RALUSLS) and sacrocolpopexy (RALSC). METHODS: Observational data for RALUSLS (n = 23) and RALSC (n = 25) collected between August 2014 and March 2016 from a single institute (The University of Texas Medical Branch) were evaluated retrospectively. Patient characteristics, concomitant procedures, and the occurrence of lower urinary tract, pelvic pain, and bowel symptoms were compared between patients undergoing RALUSLS and RALSC. RESULTS: There was no significant difference in background characteristics between the 2 groups, except for parity, which was high in the RALUSLS group. In the RALUSLS group, patients experienced significant resolution of urinary urgency (P < .001) and frequency, urge and mixed incontinence, and pelvic pain (P < .05). In the RALSC group, there was significant resolution of nocturia, mixed incontinence, pelvic pain, and dyspareunia (P < .05). There was no significant difference in the occurrence of de novo symptoms in the RALUSLS and RALSC groups (P > .05), although newly appearing urinary urgency or frequency and stress or urge incontinence were more common after RALSC. CONCLUSION: Mixed incontinence and pelvic pain improved significantly in patients after RALUSLS or RALSC. In RALUSLS patients, urgency, frequency, and urge incontinence also improved, whereas additional improvement in nocturia and dyspareunia was evident only in RALSC patients. De novo LUTS developing after these procedures, especially after RALSC, necessitate careful patient consultation prior to surgery.

RESUMO

OBJECTIVE: Overactive bladder (OAB) affects 16.9% of women in the United States. Percutaneous tibial nerve stimulation (PTNS) is a third-line treatment for patients who are refractory to behavioral and pharmacologic therapies. We aimed to evaluate the effects of PTNS on urinary symptoms in patients diagnosed as having refractory OAB and investigate the cost of medications and clinical visits before and after PTNS treatment. MATERIAL AND METHODS: We reviewed 60 women with refractory OAB treated with PTNS. Episodes of urinary frequency, leakage, urgency, and nocturia; number of follow-up visits; and medications were recorded. The mean quarterly drug, physician, nurse, and provider costs were calculated. The episodes of urinary symptoms, numbers of follow-up visits, and costs of medications and visits before and after PTNS were compared. RESULTS: Of the 60 patients with refractory OAB, 24 patients who completed 12 weekly sessions of initial PTNS were evaluated. The number of urinary symptoms and follow-up visits significantly decreased after PTNS (p<0.05). The average quarterly medication cost decreased from $656.36±292.45 to $375.51±331.79 after PTNS (p=0.001). After PTNS, quarterly physician and nurse visit costs decreased from $81.73±70.39 to $25.89±54.40 and from $55.23±38.32 to $15.53±19.58, respectively (p<0.05). The quarterly total provider cost was similar before and after PTNS. CONCLUSION: PTNS treatment significantly improved urinary symptoms of patients with refractory OAB and reduced the costs of medications and physician and nurse visits.
