The purpose of the two pilot studies was to determine the feasibility and safety of using less-radical fertility-preserving surgery: laparoscopic lymphadenectomy with sentinel lymph node identification (SLNI) followed by a large cone or simple trachelectomy (LAP-I protocol) and the LAP-III protocol, which includes neoadjuvant chemotherapy (NAC). LAP-I: Forty women underwent laparoscopic SLNI, frozen-section analysis, and a complete pelvic lymphadenectomy as the first step of treatment. Seven days after final histopathological processing of dissected nodes, a large cone or simple vaginal trachelectomy was performed in patients with negative nodes. Nine women had a tumor larger than 20 mm, prompting the administration of three cycles of NAC before surgery. LAP-I: Six frozen sections were positive (15%). In these cases, a type III Wertheim was immediately performed. There were no false-negative SLNs. There was one central recurrence, but after chemoradiation therapy, there was no evidence of the disease 62 months post-treatment. Twenty-four of 32 women whose reproductive ability had been maintained tried to conceive. Of these 24 women, 17 became pregnant (71% pregnancy rate). Eleven mothers gave birth to 12 children (1 at 24 weeks, 1 at 34 weeks, 1 at 36 weeks, and 9 between 37 and 39 weeks). LAP-III: Nine patients were included. In 7 of these 9 women, reproductive ability was maintained, with 3 women becoming pregnant (1 full term and 2 ongoing). SLNI improves safety in fertility-sparing surgery. Large cone or simple trachelectomy combined with laparoscopic pelvic lymphadenectomy can be a feasible method that yields a high, successful pregnancy rate. NAC followed by fertility-sparing surgery is an experimental alternative treatment for larger tumors.

OBJECTIVE The purpose of this pilot study was to evaluate the feasibility and safety of a less radical surgery; laparoscopic lymphadenectomy followed by a simple vaginal hysterectomy in sentinel lymph node (SLN) negative early cervical cancer patients. Treatment-associated morbidity and oncological outcome were evaluated. PATIENTS AND METHODS From December 2000 to September 2007, 60 patients (50 squamous and 10 adenocarcinoma patients) in stages 3-IA1, 11-IA2 and 46-IB1 with median age of 44.6 years (range 33-64 years) were enrolled. Patients were selected based on favorable cervical tumors (IA1 with lymph-vascular space invasion [LVSI], IA2 and IB1 with tumor size less than 20 mm and less than half of stromal invasion). All patients underwent laparoscopic SLN identification using frozen section (FS). Negative SLN patients underwent complete pelvic laparoscopic lymphadenectomy and vaginal hysterectomy. FS positive patients underwent radical hysterectomy with low paraaortic lymphadenectomy. RESULTS The average number of sentinel nodes per side was 1.4 with detection rate per side of 95%. The average number of removed nodes was 23.2. Five patients (8.3%) were SLN positive. There were two false negative FS results (both were micrometastases in SLN). Median follow-up was 47 months (range 12-92). There were no recurrences in 55 SLN negative patients and in 5 SLN positive patients. CONCLUSION Lymphatic mapping and SLN identification improved safety in less radical surgery in early stage cervical cancer. This preliminary study showed that it is both feasible and safe to reduce the radicality of parametrial resection for small tumor volume in SLN negative patients. Results also indicated that treatment-associated morbidity is low.

The influence of combined oral contraceptives on female sexual desire: A systematic review

Zlatko Pastor; Katerina Holla; Roman Chmel

ABSTRACT Objectives To determine the relationship between the use of combined oral contraceptives (COCs) and sexual desire based on a systematic review of the literature. Methods MEDLINE Complete, Google Scholar and the Cochrane Library were searched for articles published between 1975 and 2011, reporting the effects of oral contraceptives on sexual desire. Reports fully meeting all the predefined criteria were analysed and included in a final reference list. In addition, a review of the reference list of selected articles was carried out. Results We evaluated 36 studies (1978–2011; 13,673 women). Of the COC users (n = 8,422), 85% reported an increase (n = 1,826) or no change (n = 5,358) in libido and 15% reported a decrease (n = 1,238). We found no significant difference in sexual desire in the case of COCs with 20–35 μg ethinylestradiol; libido decreased only with pills containing 15 μg ethinylestradiol. Conclusions The majority of COC users report no significant change in libido although in most studies a decline in plasma levels of free testosterone and an increase in those of sex hormone binding globulin were observed.

Background Lower-limb lymphedema is one of the most disabling adverse effects of vulvar cancer surgery. Multifrequency Bioelectrical Impedance Analysis (MFBIA) is a modern noninvasive method to detect lymphedema. The first aim of this study was to prospectively determine the prevalence of secondary lower-limb lymphedema after surgical treatment for vulvar cancer using objective methods, circumference measurements and MFBIA technique. The second aim was to compare quality of life (QoL) before and 6 months after vulvar surgery. Methods Twenty-nine patients underwent vulvar cancer surgery in our study: 17 underwent inguinofemoral lymphadenectomy (RAD), and 12 underwent sentinel lymph node biopsy (CONS). Patients were examined before and 6 months after vulvar surgery by measuring the circumference of the lower limbs and with MFBIA. A control group of 27 healthy women was also measured. To evaluate QoL, the European Organisation for Research and Treatment of Cancer (EORTC) QoL questionnaires (QLQ-C30 and QLQ-CX24) were administered to patients before and 6 months after surgery. Results Using circumference measurement, 9 lymphedemas (31%) were diagnosed: 3 (25%) in the CONS and 6 (37.5%) in the RAD group (P = 0.69). After vulvar surgery, patients in the RAD group reported more fatigue and worsening of physical and role functioning. When comparing both groups, the RAD group had significantly worse parameters in social functioning, fatigue, and dyspnea. Conclusions Lower radicality in inguinofemoral lymphadenectomy shows a trend toward lower morbidity and significantly improves QoL. Multifrequency Bioelectrical Impedance Analysis was tested in these patients as a noninvasive, objective method for lymphedema detection. Detection of lymphedema based on subjective evaluations proved to have an unsatisfactory sensitivity. Less radical surgery showed objectively better results in QoL.

Objective: Lymphedema is a severe postoperative complication in oncological surgery. Multifrequency bioelectrical impedance analysis (MFBIA) is a new method for early lymphedema detection. The objective was to establish the methodology of MFBIA for lower-limb lymphedema and to detect a lymphedema in patients undergoing cervical cancer surgery. Methods: From a population of 60 patients undergoing cervical cancer surgery, 39 underwent radical hysterectomy Wertheim III (RAD group), and 21 underwent conservative surgery (laparoscopic lymphadenectomy plus simple trachelectomy/simple hysterectomy - CONS group). A control group of 29 patients (CONTR group) was used to determine the SD of impedance at zero frequency (R 0). Patients were examined before surgery and at 3 and 6 months after surgery by MFBIA and by measuring the circumference of the lower limbs. Results: No differences were found between the CONS and RAD groups on age, height, weight, and histopathologic type of tumor. However, the number of dissected lymph nodes differed significantly between the groups (17.3 in the CONS group vs 25.8 in the RAD group, P = 0.0012). The SD of R 0 in the CONTR group was 36.0 and 39.0 for the right and the left leg, respectively. No difference in prevalence of lymphedema based on circumference method was found (35.9% in the RAD and 47.6% in the CONS groups, not statistically significant). Conclusions: No difference in the prevalence of lymphedema was found between the CONS and RAD groups. A methodology for MFBIA for the detection of lower-limb lymphedema was described.

Objective The aim of this study was to prospectively monitor the patients’ quality of life (QoL) after vulvar cancer surgery. Design The design was prospective clinical study. Setting The study was set in the Department of Obstetrics and Gynecology, 2nd Medical Faculty of the Charles University and University Hospital Motol, Prague, Czech Republic. Methods A group of 36 patients underwent vulvar cancer surgery: 24 patients were subject to inguinofemoral lymphadenectomy (RAD) and 12 to sentinel lymph node biopsy. To evaluate QoL, the European Organisation for Research and Treatment of Cancer, QoL questionnaires (QLQ-C30 and QLQ-CX24) were administered to patients before and 6 and 12 months after surgery. Results In patients with vulvar cancer after inguinofemoral lymphadenectomy, increased fatigue and impaired lymphedema were observed. In the group of patients after sentinel lymph node biopsy, none of the QoL variables worsened postoperatively. Comparing both groups 12 months after surgery, the RAD group had significantly worse outcomes in body image and cognitive functioning than the sentinel lymph node biopsy group. Patients in the RAD group, who received adjuvant radiotherapy (n = 13), had worse QoL in symptom experience (P < 0.05) at 6 and 12 months after the surgery than patients without radiotherapy (n = 11). Conclusions Less radical surgery showed objectively better QoL results.

STUDY OBJECTIVE The goal of this study was to assess a group of women with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome with surgically created neovaginas in the interest of uterus transplantation (UTx) and to recruit the first group of applicants for a UTx trial. DESIGN AND SETTING This was an original prospective study using semistructured interviews. PARTICIPANTS A study group of 50 women with MRKH syndrome with Vecchietti neovaginas was recruited via letter of invitation. INTERVENTIONS AND MAIN OUTCOME MEASURES Interest of MRKH women in obtaining experimental UTx for the treatment of absolute uterine factor infertility. RESULTS A total of 50 women responded via e-mail and 31 (62% [31 of 50] of the study group) expressed serious interest in UTx after complete information about its risks and benefits was provided during the first semistructured interview. They subsequently agreed to participate in additional interviews and further examinations. Because of various reasons, only 9 women were prepared to enter our UTx trial (18% [9 of 50] of the study group). Three recipients/donors were accepted into the living donor arm and 6 into the deceased brain donor arm of the trial. CONCLUSION Nearly two-thirds of our MRKH syndrome study group women with surgically created neovaginas were interested in UTx and motivated to undergo this method of absolute uterine factor infertility treatment. Therefore, this group of women might be approached to participate in ongoing and future UTx trials. Future studies of women with MRKH syndrome might confirm or disprove the results of our survey.

Differential diagnostics of female “sexual” fluids: a narrative review

Zlatko Pastor; Roman Chmel

Introduction and hypothesisWomen expel various kinds of fluids during sexual activities. These are manifestations of sexual arousal and orgasm or coital incontinence. This study is aimed at suggesting a diagnostic scheme to differentiate among these phenomena.MethodsWeb of Science and Ovid (MEDLINE) databases were systematically searched from 1950 to 2017 for articles on various fluid expulsion phenomena in women during sexual activities, which contain relevant information on sources and composition of the expelled fluids.ResultsAn ultra-filtrate of blood plasma of variable quantity, which is composed of transvaginal transudate at sexual stimulation, enables vaginal lubrication. Female ejaculation (FE) is the secretion of a few milliliters of thick, milky fluid by the female prostate (Skene’s glands) during orgasm, which contains prostate-specific antigen. Squirting (SQ) is defined as the orgasmic transurethral expulsion of tenths of milliliters of a form of urine containing various concentrations of urea, creatinine, and uric acid. FE and SQ are two phenomena with different mechanisms. Coital incontinence (CI) could be classified into penetration and orgasm forms, which could be associated with stress urinary incontinence or detrusor hyperactivity.ConclusionSquirting, FE, and CI are different phenomena with various mechanisms and could be differentiated according to source, quantity, expulsion mechanism, and subjective feelings during sexual activities.

Sexual Life of Women With Mayer-Rokitansky-Küster-Hauser Syndrome After Laparoscopic Vecchietti Vaginoplasty

Zlatko Pastor; Jiří Froněk; Marta Novackova; Roman Chmel

Introduction Adequate anatomic and physiologic functions of the genitalia are fundamental prerequisites for sexual well-being and reproduction. Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) compromises female sexual life and makes reproduction impossible. Aim To assess the psychosexual effect of vaginal reconstruction using the laparoscopic Vecchietti technique in patients with MRKHS. Methods Forty-two patients with MRKHS who underwent laparoscopic Vecchietti vaginoplasty were included. Their partners also were interviewed. A control group of 45 age-matched, childless, sexually active women were examined during the same period. Main Outcome Measures A gynecologic examination was performed to determine the anatomic outcome. Psychosexual function was evaluated with the Female Sexual Distress Scale–Revised (FSDS-R), the Female Sexual Function Index (FSFI), and a semistructured interview. Genital self-image was evaluated using the Female Genital Self-Image Scale (FGSIS). Results Average neovagina length (7.0 ± 9.6 cm) in the MRKHS group was significantly shorter than the vaginal length in the control group (9.3 ± 2.5 cm). Women with a neovagina reported satisfactory sexual function (FSFI score = 29 ± 2.7) that was not significantly different from the control group (P < .05); however, they also had significantly higher levels of distress (FSDS-R score = 14.5 ± 6.5) and were not satisfied with their genitals (FGSIS score = 22.0 ± 2.4) compared with the control group. Conclusion Sexual function in women with MRKHS can be restored successfully by vaginoplasty; however, they have higher rates of distress and are less satisfied with their genitals.
