Persistence or recurrence of symptoms after transurethral resection of the prostate: a urodynamic assessment

The Journal of Urology
E K SeamanS A Kaplan

Abstract

Approximately 15 to 20% of patients who undergo transurethral resection of the prostate for benign prostatic hyperplasia have persistent or recurrent voiding symptoms requiring further therapy. To elucidate the etiology of these voiding abnormalities, the urodynamic findings of 129 consecutive men (mean age 72 years) with post-transurethral resection voiding symptoms were retrospectively analyzed with respect to symptoms, uroflowmetry and synchronous video pressure-flow cystometry. Our findings revealed obstruction in 38% of the patients, impaired contractility in 25% and intrinsic sphincter deficiency in 8%. Among 80 patients without neurological disorders involuntary bladder contractions were detected in 50%. However, in 49 patients with neurological disorders involuntary bladder contractions were detected in 76%. This difference was statistically significant. There were 15 patients who failed 2 or more transurethral resections of the prostate, and involuntary bladder contractions were detected in 80%, obstruction in 27%, impaired contractility in 27% and sphincteric incontinence in 20%. Our study reveals residual or recurrent obstruction to be a contributing factor in less than half of all patients who fail transurethral res...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
