“…PVR ≥ 200 ml is a sign of incomplete bladder emptying not CESR and is consistent with retention of executive control of the bladder. An ideal PVR is 0 ml, but in young adults, < 50 ml is normal; a PVR of up to 100 ml can be normal in older adults; > 200 ml is incomplete bladder emptying [ 15 ]. Anecdotally, we were aware of patients with PVRs of ≤ 200 ml who had a large compressive disc prolapse.…”

Objective Post-void residual (PVR) scans of less than 200 ml are increasingly being used to rule out the likelihood of cauda equina syndrome (CES) and to delay emergency MRI scanning in suspected cases. This study was done to review a series of 50 MRI confirmed cases of CES and to test the hypothesis that a PVR of less than 200 ml was unlikely to be present. Methods Fifty consecutive medicolegal cases involving CES were audited. Records were reviewed to see if PVR scans were done. MRI scans were reviewed, clinical and radiological diagnosis reviewed, and treatment recorded. Results Out of 50 CES cases, 26 had had PVR scans. In 14/26 (54%) the PVR scan was ≤ 200 ml. In one case, the CES diagnosis was in question leaving 13/26 (50%) cases where there was a clear clinical and MRI diagnosis of CES despite the PVR being ≤ 200 ml. All 13 were classified as incomplete cauda equina syndrome (CESI) and all proceeded to emergency decompression. Conclusions This study is the first in the literature to demonstrate that there is a significant group of CES patients who require emergency decompression but have PVRs ≤ 200 ml. The results demonstrate the existence of a significant group of CESI patients whose bladder function may be deteriorating, but they have not yet reached the point where the PVR is over 200 ml. Given the accepted understanding that CESI is best treated with emergency decompression, such patients are likely to have worse outcomes if MRI scanning and therefore surgery is delayed. We recommend the following: PVR is recommended as an assessment tool in suspected CES. A PVR of ≤ 200 reduces the likelihood of having CES but does not exclude it; clinical suspicion of CES should always lead to an MRI scan. Further investigation of PVR as a prognostic tool is recommended.

“… 12 During instillations, UIC was defined as an obvious change in detrusor pressure (≥15 cmH 2 O), and BS was conceptualized as the awareness of bladder filling and increasing sensation up to a desire to void, which numerically equals the first sensation volume (<100 ml, sensitive; 100–200 ml, good; and >200 ml, reduced). 13 14 BOOI 15 was calculated as PdetQmax−2×Qmax, and patients were divided into mild (<20), moderate (20–40), and severe (>40) BOOI groups. URA was calculated as ([1+4dQ 2 ×PdetQmax] 1/2 –1)/(2dQmax 2 ), wherein d=3.8×10 −4 , and patients were divided into ≥28.9884 cmH 2 O and <28.9884 cmH 2 O groups.…”

We investigated the impact and predictive value of bladder function in patients with benign prostatic hyperplasia (BPH) on the efficacy of transurethral prostatectomy. Symptomatic, imaging, and urodynamic data of patients who underwent transurethral prostatectomy at West China Hospital of Sichuan University (Chengdu, China) from July 2019 to December 2021 were collected. Follow-up data included the quality of life (QoL), International Prostate Symptom Score (IPSS), and IPSS storage and voiding (IPSS-s and IPSS-v). Moreover, urinary creatinine (Cr), nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), and prostaglandin estradiol (PGE2) were measured in 30 patients with BPH and 30 healthy participants. Perioperative indicators were determined by subgroup analyses and receiver operating characteristic (ROC) curve analysis. Among the 313 patients with BPH included, patients with severe micturition problems had more improvements but higher micturition grades postoperatively than those with moderate symptoms. Similarly, good bladder sensation, compliance, and detrusor contractility (DC) were predictors of low postoperative IPSS and QoL. The urinary concentrations of BDNF/Cr, NGF/Cr, and PGE2/Cr in patients were significantly higher than those in healthy participants (all P < 0.001). After evaluation, only DC was significantly related to both urinary indicators and postoperative recovery of patients. Patients with good DC, as predicted by urinary indicators, had lower IPSS and IPSS-v than those with reduced DC at the 1st month postoperatively (both P < 0.05). In summary, patients with impaired bladder function had poor recovery. The combined levels of urinary BDNF/Cr, NGF/Cr, and PGE2/Cr in patients with BPH may be valid predictors of preoperative bladder function and postoperative recovery.

AimsLower urinary tract (LUT) sensations form an essential part of diagnostic criteria for many LUT symptoms, additionally LUT sensations are used to evaluate the effectivity of therapeutic interventions. The accurate measurement of LUT sensations, however, is severely hampered by the subjective nature of these sensations.MethodsThis paper summarizes the discussions from the 2024 meeting of the International Consultation for Incontinence‐Research Society (ICI‐RS 2024) regarding systematic evaluations of LUT sensations and the design of more objective tools to measure these.ResultsHere, we discuss factors that influence sensations that are under the control of the caregiver/investigator, the signaling of sensations from the LUT toward the central nervous system, and currently used diagnostic tools to measure LUT sensations. Recent methodological advances to objectively measure factors that correspond with changes in LUT sensations are introduced along with recommendations for future research to optimally enable objective assessment of processes underlying LUT sensations.ConclusionsAdvancing the objective measurement of LUT sensations will require interdisciplinary collaboration, integrating insights from neuroscience, engineering, and clinical practice. Such efforts hold the potential to transform patient care by enabling more precise diagnostics and personalized therapeutic strategies.

Methods of assessing and recording bladder sensation: a review of the literature

Abstract: In some of the studies, the samples were too small to draw any significant conclusions. There were also conflicting data on which tool was the most accurate, especially as each method of evaluating bladder sensation may influence the way it is described by participants.
