Clinical utility of hyperbaric oxygen therapy in genitourinary medicine.

Med Gas Res 2018 Jan-Mar;8(1):29-33. Epub 2018 Apr 18.

Department of Physiology and Biophysics, Stony Brook University School of Medicine, Stony Brook, NY, USA.

Hyperbaric oxygen therapy (HBOT) is a medical technique which delivers oxygen at ambient pressures to increase the amount of dissolved oxygen in the blood and oxygen distribution to tissues. There are several beneficial properties of HBOT concomitant with elevated oxygen distribution in tissue including anti-inflammation, angiogenesis through vascular endothelial growth factor proliferation, augmented fibroblast activity through fibroblast growth factor proliferation, tissue and wound repair, enhancement of lymphocyte and macrophage activity, increased male testosterone secretion, and bactericidal activity. Given its renown in treating conditions such as decompression sickness and carbon monoxide poisoning, HBOT is making gradual strides for use in genitourinary medicine due to its low risk and likeliness to achieve favorable results.

Changes in the Neuronal Control of the Urinary Bladder in a Model of Radiation Cystitis.

J Pharmacol Exp Ther 2018 May 12;365(2):327-335. Epub 2018 Mar 12.

Department of Pharmacology, Institution of Neuroscience and Physiology (D.G., L.P., G.T.) and Department of Oncology, Institution of Clinical Sciences, University of Gothenburg, Gothenburg, Sweden (D.G.); and Department of Medical Biochemistry, Faculty of Medicine, Charles University, Hradec Králové, Czech Republic (L.P.).

Currently, we have assessed the neuronal control of the urinary bladder in radiation cystitis and whether interstitial cells contribute to the condition. Fourteen days after bladder irradiation (20 Gy), rats were sedated and the urinary bladder was cut into two sagittal halves where electrical field stimulation (EFS; 5-20 Hz) was applied on the pelvic nerve afferents or stretch (80 mN) on one-half of the bladder, while contractions were registered on the contralateral half of the bladder in the absence and presence of increasing doses of imatinib (1-10 mg/kg; inhibitor of c-kit-positive interstitial cells), atropine (1 mg/kg; to block muscarinic M receptors), or pyridoxalphosphate-6-azophenyl-2',4'-disulfonic acid (2 mg/kg; P2 purinoceptor antagonist). Urinary bladders were also excised for organ bath experiments, Western blot, quantitative polymerase chain reaction, and immunohistochemistry. Read More

Acute radiation impacts contractility of guinea-pig bladder strips affecting mucosal-detrusor interactions.

PLoS One 2018 7;13(3):e0193923. Epub 2018 Mar 7.

Centre for Cancer Research and Cell Biology, School of Medicine, Dentistry and Biomedical Sciences, Queen's University Belfast, Belfast, Northern Ireland, United Kingdom.

Radiation-induced bladder toxicity is associated with radiation therapy for pelvic malignancies, arising from unavoidable irradiation of neighbouring normal bladder tissue. This study aimed to investigate the acute impact of ionizing radiation on the contractility of bladder strips and identify the radiation-sensitivity of the mucosa vs the detrusor. Guinea-pig bladder strips (intact or mucosa-free) received ex vivo sham or 20Gy irradiation and were studied with in vitro myography, electrical field stimulation and Ca2+-fluorescence imaging.

3-Piece Inflatable Penile Prosthesis Placement Following Radical Cystoprostatectomy and Urinary Diversion: Technique and Outcomes.

J Sex Med 2018 Jun 13;15(6):907-913. Epub 2018 Feb 13.

USC Institute of Urology, USC/Norris Comprehensive Cancer Center, Keck School of Medicine, University of Southern California, Los Angeles, CA, USA.

Background: After radical cystoprostatectomy (RC), postoperative erectile dysfunction (ED) is a common consequence with multiple contributing etiologies. The inflatable penile prosthesis (IPP) offers patients a definitive treatment option when ED is refractory to medical therapies. Because of the hostile postoperative anatomy of these patients, a careful surgical approach is necessary for successful outcomes and to avoid adjacent organ injury. Read More
