Age- and gender-specific normal post void residual urine volume in healthy adolescents

Lim LY, Chang SJ, Yang SS

J Pediatr Urol, 2023 Aug;19(4):367.e1-367.e6.
PMID: 37029009 DOI: 10.1016/j.jpurol.2023.03.026

INTRODUCTION: Elevated post void residual (PVR) is a significant risk factor for urinary tract infections (UTI). It is also a significant predictor of treatment outcomes in cases of vesicoureteral reflux, pediatric enuresis, and non-neurogenic LUT dysfunction. However, the absence of age-specific nomograms for adolescents may limit PVR's use in clinical practice.
OBJECTIVE: To establish age- and gender-specific normal PVR urine volume in adolescents.
MATERIAL AND METHODS: Healthy adolescents aged 12-18 years were recruited to undergo two uroflowmetry and PVR studies whenever they felt the urge to urinate. Adolescents with neurological disorders, known LUT dysfunction or UTI were excluded.
RESULTS: A total of 1050 adolescents were invited, but only 651 consented. Fourteen participants were excluded due to low bladder volume (BV 100 ml (n = 5) and missing information (n = 6). Ultimately, 894 uroflowmetry and PVR from 605 adolescents (mean age 14.6 ± 1.5 years) were analyzed. PVRs were higher in adolescents aged 15-18 years than in those aged 12-14 years (P 20 ml (7% BV) for males of both the age groups, and PVR >25 ml (9% BV) and PVR >35 ml (>10% BV) for females aged 12-14 and 15-18 years, respectively. Further investigation may be warranted if the repeat PVR is above the 95th percentile, i.e., PVR >30 ml (8% BV) and >30 ml (11% BV) for males aged 12-14 and 15-18 years, respectively, and PVR >35 ml (11% BV) and >45 ml (13% BV) for females aged 12-14 and 15-18 years, respectively.
CONCLUSION: PVR increases with age and varies by gender; thus, age-and gender-specific reference values should be used. Further data from other countries is required to determine whether the study's recommendations can be applied globally.
Methyl Palmitate Modulated NMDA-Induced Cerebral Hyperemia in Hypertensive Rats

N-methyl-D-aspartate (NMDA) receptors were found to be dysfunctional in hypertensive rats. Methyl palmitate (MP) has been shown to diminish the nicotine-induced increase in blood flow in the brainstem. The aim of this study was to determine how MP modulated NMDA-induced increased regional cerebral blood flow (rCBF) in normotensive (WKY), spontaneously hypertensive (SHR), and renovascular hypertensive (RHR) rats. The increase in rCBF after the topical application of experimental drugs was measured using laser Doppler flowmetry. Topical NMDA application induced an MK-801-sensitive increase in rCBF in anesthetized WKY rats, which was inhibited by MP pretreatments. This inhibition was prevented by pretreatment with chelerythrine (a PKC inhibitor). The NMDA-induced increase in rCBF was also inhibited by the PKC activator in a concentration-dependent manner. Neither MP nor MK-801 affected the increase in rCBF induced by the topical application of acetylcholine or sodium nitroprusside. Topical application of MP to the parietal cortex of SHRs, on the other hand, increased basal rCBF slightly but significantly. MP enhanced the NMDA-induced increase in rCBF in SHRs and RHRs. These results suggested that MP had a dual effect on the modulation of rCBF. MP appears to play a significant physiological role in CBF regulation.

J Gynecol Oncol, 2015 Jan;26(1):68-74.
PMID: 25609163 DOI: 10.3802/jgo.2015.26.1.68

The Asian Society of Gynecologic Oncology International Workshop 2014 on gynecologic oncology was held in Asan Medical Center, Seoul, Korea on the 23rd to 24th August 2014. A total of 179 participants from 17 countries participated in the workshop, and the up-to-date findings on the management of gynecologic cancers were presented and discussed. This meeting focused on the new trends in the management of cervical cancer, fertility-sparing management of gynecologic cancers, surgical management of gynecologic cancers, and recent advances in translational research on gynecologic cancers.

The Asian Society of Gynecologic Oncology International Workshop 2018 on gynecologic oncology was held in the Ajou University Hospital, Suwon, Korea on the 24th to 25th August 2018. The workshop was an opportunity for Asian doctors to discuss the latest findings of gynecologic cancer, including cervical, ovarian, and endometrial cancers, as well as the future of fertility-sparing treatments, minimally invasive/radical/debulking surgery, radiotherapy, chemotherapy, targeted therapy, and immunotherapy. Clinical guidelines and position statement of Asian countries were presented by experts. Asian clinical trials for gynecologic cancers were reviewed and experts emphasized the point that original Asian study is beneficial for Asian patients. In Junior session, young gynecologic oncologists presented their latest research on gynecologic cancers.
