Full-term newborn after repeated ovarian tissue transplants in a patient treated for Ewing sarcoma by sterilizing pelvic irradiation and chemotherapy.

Acta Obstet Gynecol Scand 2015 Mar 2;94(3):324-8. Epub 2015 Feb 2.

We report the first successful transplantation of cryopreserved ovarian cortical tissue into heavily irradiated tissues in a patient who had received sterilizing pelvic radiotherapy (54 Gy) and 40 weeks of intensive high-dose chemotherapy for the treatment of Ewing's sarcoma 14 years earlier. Repeated transplantation procedures were required to obtain fully functional follicular development. Enlargement of the transplants over time and increase of the size of the uterus were demonstrated on sequential ultrasonographic examinations. Eggs of good quality that could be fertilized in vitro were obtained only after a substantial incremental increase of the amount of ovarian tissue transplanted. Single embryo replacement resulted in a normal pregnancy and the birth of a healthy child by cesarean section at full-term. No neonatal or maternal postoperative complications occurred. Women facing high-dose pelvic radiotherapy should not be systematically excluded from fertility preservation options, as is currently the trend.

Urodynamic assessment of anterior vaginal wall surgery: a randomized comparison between colporraphy and transvaginal mesh.

Neurourol Urodyn 2010 Apr;29(4):527-31

Division of Obstetrics and Gynaecology, Department of Clinical Science and Education, Karolinska Institutet, Södersjukhuset, Stockholm, Sweden.

Aims: To investigate the urodynamic effects of anterior vaginal wall prolapse surgery using either trocar guided transvaginal mesh or colporraphy.

Methods: A prospective, randomized multicenter trial enrolling 50 patients: 27 underwent anterior colporrhaphy and 23 anterior trocar guided transvaginal mesh. Urodynamic assessment was performed pre- and two months postoperatively.

Results: De novo stress urinary incontinence was significantly more common after trocar guided transvaginal mesh surgery compared to colporraphy. In comparison to baseline urodynamics, transvaginal mesh surgery resulted in a significant decrease in maximal urethral closing pressures (MUCP) whereas conventional anterior colporraphy had no significant effect on urodynamic parameters.

Conclusion: Trocar guided transvaginal mesh of anterior vaginal wall prolapse results in a lowering of MUCPs and increases the risk for de novo stress urinary incontinence compared to colporraphy.

Desmopressin in the treatment of nocturia: a double-blind, placebo-controlled study.

Eur Urol 2007 Jul 16;52(1):221-9. Epub 2007 Jan 16.

Department of Urology, University Hospital Maastricht, The Netherlands.

Objectives: To investigate efficacy, safety, and impact on quality of sleep of desmopressin in the treatment of nocturia.

Methods: Adults aged > or =18 yr with nocturia (> or =2 voids/night) received desmopressin tablets (0.1, 0.2, or 0.4 mg) during a 3-wk dose-titration period. Patients should show sufficient response during the dose-titration period (> or =20% reduction in nocturnal diuresis) and a return of nocturnal diuresis to > or =80% of baseline levels during washout. Eligible patients then entered a 3-wk double-blind treatment period and received either desmopressin or placebo.

Results: 127 patients were randomised to either desmopressin (n=61) or placebo (n=66). Twenty (33%) desmopressin-treated patients compared with seven (11%) placebo-treated patients showed a clinical response, defined as a > or =50% reduction in the number of nocturnal voids compared with baseline (p=0.0014). Compared with placebo, desmopressin resulted in a significant reduction in the mean number of nocturnal voids (39% reduction with desmopressin vs. 15% with placebo; absolute difference -0.84, p<0.0001) and duration of the first sleep period (prolonged by 108 min with desmopressin vs. 41 min with placebo; p<0.0001). Quality of sleep was also improved with desmopressin versus placebo (statistically significant for one of the two parameters evaluated). Adverse events were mainly mild.

Conclusions: Oral desmopressin tablets provide an effective and well-tolerated treatment for nocturia. Compared with placebo, nocturnal voiding frequency is reduced, duration of the first sleep period is increased, and sleep quality may be improved.

A 3-month preclinical trial to assess the performance of a new TVT-like mesh (TVTx) in a sheep model.

Int Urogynecol J Pelvic Floor Dysfunct 2007 Feb 21;18(2):183-7. Epub 2006 Apr 21.

Department of Women's and Children's Health Obstetrics and Gynecology, Uppsala University, Uppsala, Sweden.

The objective of this study was to evaluate in a sheep model the performance of a new polypropylene mesh (TVTx), which is intended as a less invasive treatment for female stress urinary incontinence. Eight female sheep were used in this study, each one being implanted with eight TVTx samples. At each time-point (weeks 1, 2, 4, and 12) seven TVTx were pulled out, while one TVTx was carefully dissected for histological investigations. One TVTx and one TVT, moreover, were inserted and immediately pulled out for obtaining the initial pullout forces in all sheep. The initial pullout values of TVT and TVTx were overlapping. The pullout forces of TVTx were >5 N (500 g) and increasing from weeks 1 to 12 (p<0.001). Histology revealed good tissue integration of TVTx in the tissue within 12 weeks after implantation. No abnormal histological findings were observed. This data could support the realization of a clinical trial with the TVTx mesh.

Seven-year follow-up of the tension-free vaginal tape procedure for treatment of urinary incontinence.

Obstet Gynecol 2004 Dec;104(6):1259-62

Department of Obstetrics and Gynecology, Helsinki University Central Hospital, Helsinki, Finland.

Objective: To evaluate the long-term cure rates and late complication rates after treatment of female urinary stress incontinence with the minimally invasive tension-free vaginal tape operation.

Methods: Prospective observational, 3-center cohort study originally of 90 women requiring surgical treatment for primary urinary stress incontinence. Assessment variables included a 24-hour pad weighing test, a stress test, visual analog scale for assessing the degree of bother, and a questionnaire assessing the subjective perception of the women on their continence status.

Results: The follow-up time was a mean of 91 months (range 78-100 months). Both objective and subjective cure rates were 81.3% for the 80 women available for follow-up. Asymptomatic pelvic organ prolapse was found in 7.8%, de novo urge symptoms in 6.3%, and recurrent urinary tract infection in 7.5% of the women. No other long-term adverse effects of the procedure were detected.

Conclusion: The tension-free vaginal tape procedure for treatment of female urinary stress incontinence is effective over a period of 7 years.
