Pelvic floor muscle strength is correlated with sexual function
Dulcegleika Vilas Boas Sartori,Paulo Roberto Kawano,Hamilto Akihissa Yamamoto,Rodrigo Guerra,Pedro Rochetti Pajolli,João Luiz Amaro 대한비뇨의학회 2021 Investigative and Clinical Urology Vol.62 No.1
Purpose: Sexual performance is related to proprioception and pelvic floor muscle strength (PFMS). The aim of this study was to correlate sexual activity and orgasm with PFMS. Materials and Methods: A total of 140 healthy continent female were prospectively distributed into 4 groups according to age: Group 1 (G1), 30–40; Group 2 (G2), 41–50; Group 3 (G3), 51–60; Group 4 (G4), over 60 years old. Evaluated parameters were: frequency of sexual activity and orgasm achievement; body mass index (BMI) and objective evaluation of PFMS using perineometer and surface electromyography. Results: BMI was higher in G4 compared to G1 (p=0.042). Women who reported sexual activity was significantly higher in G1 compared to G3 and G4 (94.1% vs. 66.7% and 37.5%, respectively; p=0.001). Orgasm was more frequently in G1 compared to G3 and G4 (91.2% vs. 63.9% and 28.1%, respectively; p=0.001), demonstrating that sexual activity and orgasm decrease after age 51. The duration of PFM contraction was significantly higher in women who had sexual intercourse (p=0.033) and orgasm (p=0.018). Conclusions: Although the frequency of sexual intercourse and orgasm may decrease with aging, a relationship between sexual activity and PFMS remains apparent, once both sexually active women and those who have orgasms showed better PFM endurance than non-sexually active ones.

What Is the Ideal Core Number for Ultrasound-Guided Prostate Biopsy?

Purpose: We evaluated the utility of 10-, 12-, and 16-core prostate biopsies for detectingprostate cancer (PCa) and correlated the results with prostate-specific antigen (PSA)levels, prostate volumes, Gleason scores, and detection rates of high-grade prostaticintraepithelial neoplasia (HGPIN) and atypical small acinar proliferation (ASAP). Materials and Methods: A prospective controlled study was conducted in 354 consecutivepatients with various indications for prostate biopsy. Sixteen-core biopsy specimenswere obtained from 351 patients. The first 10-core biopsy specimens were obtainedbilaterally from the base, middle third, apex, medial, and latero-lateral regions. Afterward, six additional punctures were performed bilaterally in the areas more lateralto the base, middle third, and apex regions, yielding a total of 16-core biopsyspecimens. The detection rate of carcinoma in the initial 10-core specimens was comparedwith that in the 12- and 16-core specimens. Results: No significant differences in the cancer detection rate were found between thethree biopsy protocols. PCa was found in 102 patients (29.06%) using the 10-core protocol,in 99 patients (28.21%) using the 12-core protocol, and in 107 patients (30.48%) usingthe 16-core protocol (p=0.798). The 10-, 12-, and 16-core protocols were comparedwith stratified PSA levels, stratified prostate volumes, Gleason scores, and detectionrates of HGPIN and ASAP; no significant differences were found. Conclusions: Cancer positivity with the 10-core protocol was not significantly differentfrom that with the 12- and 16-core protocols, which indicates that the 10-core protocolis acceptable for performing a first biopsy.
