Pelvic organ prolapse after 3 modes of hysterectomy: long-term follow-up.

BACKGROUND: There are various indications and approaches for hysterectomy; yet, the difference in long-term risk of subsequent prolapse after surgery is not well studied. OBJECTIVE: To assess the risk of prolapse after abdominal, vaginal, and laparoscopic or robotic hysterectomy for up to 17 years from surgery. STUDY DESIGN: A retrospective chart review study of women undergoing hysterectomy across all indications (benign and malignant) between 2001 and 2008 was conducted. An equivalent random sample of hysterectomy patients was selected each year. We compared demographic and other surgical characteristics data including age, race, parity, body mass index, indication and year of hysterectomy, blood loss, cervix removal, cuff suspension, and complications using chi-square, Kruskal-Wallis test, and Fisher's exact across the 3 groups. Presence and treatment of subsequent prolapse (based on patient symptoms, pelvic exam, International Classification of Diseases, Ninth Revision diagnosis, and current procedural terminology pessary or surgical codes) were compared with Kaplan-Meier survival analysis and Cox proportional hazards regression. RESULTS: Of the 2158 patients, 1459, 375, and 324 underwent open, vaginal, and laparoscopic or robotic hysterectomy, respectively. The vaginal group (56) was older than the abdominal (52) or laparoscopic or robotic (49) groups, with a P value of <.05. Most patients were White with a mean body mass index of 30 kg/m2. The main indication was cancer for abdominal (33%) and laparoscopic or robotic hysterectomy (25%) and prolapse for vaginal hysterectomy (60%). Time to prolapse was shortest after vaginal surgery (27 months) and longest after laparoscopic or robotic surgery (71 months). After controlling for confounders, including surgery indication, the hazard ratio for subsequent prolapse was no different among vaginal (hazard ratio=1.36 [0.77-2.45]), laparoscopic or robotic (hazard ratio=1.47 [0.80-2.69]), or open (reference) hysterectomy. Prolapse grade was similar across the 3 groups. About 50% of women with recurrent prolapse received physical therapy, pessary, or surgical treatment. CONCLUSION: At the 17-year follow-up, the route of hysterectomy is not associated with a difference in recurrence, grade, or subsequent treatment of prolapse when the indication for hysterectomy is considered. Prolapse, as an indication for hysterectomy, increases risk for recurrence. Women planning a hysterectomy should be counseled appropriately about the risk of subsequent prolapse.

Cardiomyocyte PAI-1 influences the cardiac transcriptome and limits the extent of cardiac fibrosis in response to left ventricular pressure overload.

Plasminogen activator inhibitor-1 (PAI-1) is a specific and rapid-acting inhibitor of endogenous plasminogen activators (uPA and tPA). The global PAI-1 knockout mice (PAI-1KO) develop age-dependent cardiac-selective fibrosis, and young global PAI-1KO mice exhibit augmented susceptibility to developing cardiac fibrosis in response to hypertension. Here, we tested the hypothesis that cardiomyocyte PAI-1 is necessary to provide cardioprotective effects in a left ventricular pressure overload-induced murine model of cardiac hypertrophy and fibrosis using cardiomyocyte-specific PAI-1 knockout (cmPAI-1KO) mice. The results revealed that cmPAI-1KO mice display significantly worse cardiac fibrosis than controls. To investigate the molecular mechanisms responsible for these effects, genome-wide cardiac transcriptome analysis was performed. Loss of cardiomyocyte PAI-1 led to differential expression of 978 genes compared to controls in response to left ventricular pressure overload. Pathway enrichment analysis identified the inflammatory response, cell substrate adhesion, regulation of cytokine production, leukocyte migration, extracellular matrix organization, and cytokine-mediated signaling pathways as being significantly upregulated in cmPAI-1KO hearts. Conversely, specific epigenetic repressors, cation transmembrane transport, muscle system processes, and nitric oxide signaling were significantly downregulated in cmPAI-1KO hearts compared to control hearts in response to left ventricular pressure overload. Collectively, the present study provides strong evidence of the impact of cardiomyocyte PAI-1 in regulation of the transcriptome network involved in the cardiac stress response. In response to stress, the deregulatory impact of cardiomyocyte PAI-1 loss on the cardiac transcriptome may be the underlying cause of cardiac-selective accelerated fibrogenesis in global PAI-1-deficient mice.

Intravesical Extrusion of a Single-Incision Midurethral Sling Anchor With a Simple Transurethral Resection Technique: A Case Report.

Single-incision midurethral slings were introduced in 2006 with the goal of providing shorter operative time, less postoperative pain, and decreased rates of injury to surrounding structures (eg, bladder and/or obturator nerve). Although unrecognized bladder injury during SIMS placement is a rare complication, it can lead to irritative voiding symptoms and recurrent urinary tract infections. We present the case of minimally invasive approach to remove an extruded sling.
