Objective  To evaluate in a prospective study the efficacy of interstitial radiofrequency therapy (IRFT) of the prostate in relieving acute urinary retention in patients with benign prostatic hyperplasia. Patients and methods  Twenty‐seven patients presenting in acute urinary retention who failed at least one trial of voiding one week after presentation were treated with IRFT of the prostate. During the 6‐month follow‐up, the International Prostate Symptom Score (IPSS), urinary flow rate, post‐void residual volume (PVR) and serum creatinine were determined and changes in erectile and ejaculatory functions recorded. The treatment was considered successful if the patient resumed normal voiding, without compromising renal function and without troublesome lower urinary tract symptoms necessitating further treatment. Results  Of the 26 evaluable patients, 77% resumed normal voiding. At 6 months after treatment, the mean (sd) IPSS had decreased from 15.0 (8.3) to 8 (5.4), the PVR from 950 (203) to 88 (60) mL and the maximum flow rate was 10.5 (4.36) mL/s. Conclusion  IRFT of the prostate is a safe and effective treatment, at least in the short‐term, for relieving acute urinary retention in patients with benign prostatic hyperplasia. The longer term follow‐up is continuing.

During inhalation oxygen molecules are drawn towards type I cells. The partial pressure difference and solubility factor act as a Drive for this movement of oxygen molecules.It is well known that the pulmonary surfactant plays an important role in gas exchange. The surfactant is thin mono-layer. The top surface of surfactant with SP-B and C proteins faces alveolar air and is hydrophobic in nature and acts as a surface tension reducer, whereas lower surface with SP-A and D proteins, is hydrophilic and is adsorbed on mucosal layer. This lower surface of surfactant acts as an anti invader, pathogen barrier. However there is a small missing link in explaining its exact mechanism or role in justifying these properties during normal conditions and during ‘viral ligand’ attack.Similarly a unique physical property of SP- C component is listed in research papers; however its application is not researched anywhere. SP-C has a dielectric constant of 2 to 3 and plays a very critical role in drastically reducing progression of any respiratory viral disease including SARS-CoV-2. This hypothesis targets to explain both micro mechanisms with the help of basic laws of physics, and fluid mechanics. The figures/sketches, drawn also depict the physics involved and not much of a physiology or genetic codes etc. Two examples, in the industry, are briefly listed in the last paragraphs to draw some parallel with above mechanisms.Vaccination is a proven method for containment of a particular respiratory viral disease, if not its cure. But if focus is also given on health of pulmonary surfactant with respect to pathogenesis of any respiratory viral disease, and development of a broad spectrum medication on it; probable loss of lot many lives can be avoided and vaccine development and vaccination management related issues can be less panicky.
