    Title The Extended Use of Deflux (dextranomer/hyaluronic Acid) in Pediatric Urology.
    Date July 2006
    Journal Current Urology Reports
    Excerpt

    The use of injectable bulking agents into the submucosal layer of the pediatric urinary tract continues to grow. Treatment strategies for vesicoureteral reflux and urinary incontinence have changed with the introduction of dextranomer/hyaluronic acid as a minimally invasive option. Socially and medically debilitating conditions requiring major surgical reconstruction and hospitalization in the past have now been replaced by outpatient endoscopic procedures. As experience has been gained, broader uses of this agent have been applied to more complex etiologies of reflux and incontinence.

    Title M2 and M3 Muscarinic Receptor Activation of Urinary Bladder Contractile Signal Transduction. Ii. Denervated Rat Bladder.
    Date April 2006
    Journal The Journal of Pharmacology and Experimental Therapeutics
    Excerpt

    Normal rat bladder contractions are mediated by the M(3) muscarinic receptor subtype. The M(2) receptor subtype mediates contractions of the denervated, hypertrophied bladder. This study determined signal transduction mechanisms mediating contraction of the denervated rat bladder. Denervated bladder muscle strips were exposed to inhibitors of enzymes thought to be involved in signal transduction in vitro followed by a cumulative carbachol concentration-response curve. Outcome measures were the maximal contraction, the potency of carbachol, and the affinity of darifenacin for inhibition of contraction. Inhibition of phosphoinositide-specific phospholipase C (PI-PLC) with 1-O-octadecyl-2-O-methyl-sn-glycero-3-phosphorylcholine (ET-18-OCH(3)) has no effect on denervated bladder contractions, whereas inhibition of phosphatidyl choline-specific phospholipase C (PC-PLC) with O-tricyclo[5.2.1.02,6]dec-9-yl dithiocarbonate potassium salt (D609) attenuates the carbachol maximum and potency. Inhibition of rho kinase with (R)-(+)-trans-4-(1-aminoethyl)-N-(4-pyridyl)cyclohexanecarboxamide dihydrochloride (Y-27632) reduces carbachol maximum, carbachol potency, and increases darifenacin affinity. Inhibition of rho kinase, protein kinase A (PKA), and protein kinase G (PKG) with 1-(5-isoquinolinesulfonyl)-homopiperazine.HCl (HA-1077) reduces the carbachol maximum and potency. Inhibition of PKC with chelerythrine increases darifenacin affinity, whereas inhibition of rho kinase, PKA, PKG, and protein kinase C (PKC) with 1-(5-isoquinolinesulfonyl)-2-methylpiperazine.2HCl (H7) reduces the carbachol potency while increasing darifenacin affinity. Inhibition of rho kinase, PKA, and PKG with N-[2-(p-bromocinnamylamino)ethyl]-5-isoquinolinesulfonamide.2HCl (H89) increases darifenacin affinity. This study demonstrates that different signal transduction mechanisms mediate the contractile response in the denervated rat bladder than in normal rat bladder. In normal rat bladder, PI-PLC and PC-PLC mediate the contraction, but in denervated bladder only PC-PLC is involved. In the denervated bladder, the rho kinase pathway is more dominant than in normal bladders. PKA seems to mediate a contractile response in normal bladders, whereas it seems to inhibit contraction in denervated bladders.

    Title Gunshot Wounds to the Scrotum: a Large Single-institutional 20-year Experience.
    Date
    Journal Bju International
    Excerpt

    Study Type - Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? Penetrating trauma to the scrotum often requires operative intervention, with testicular salvage only possible when enough testicular tissue can be re-approximated in the traumatic setting. The present report represents the largest series of gunshot wound trauma to the scrotum in the literature. Further, it validates recommendations of the European Association of Urology guidelines on urological trauma that advocate operative intervention due to minimal rates of patient morbidity and the inherent limitations of scrotal ultrasonography in discerning testicular compromise.
