Pelvic organ prolapse (POP) is a common condition in women. Women with POP often experience pelvic discomfort, urinary and fecal problems, sexual dysfunction, and an overall decrease in their quality of life. Surgical treatment is a feasible option if conservative management fails. Various surgical techniques have been proposed to correct POP with or without the use of graft material. Owing to recent U.S. Food and Drug Administration warnings about mesh-related complications, sacrospinous ligament fixation (SSF), as a traditional vaginal procedure, may play an important role again. To answer this question and evaluate quantitatively the efficacy of SSF in POP, we conducted a systemic review of the available data about SSF and POP. Interventions had to include SSF as a point of attachment. To eliminate confounding bias and effect modification, at least one arm must include SSF without mesh or graft. All follow-up periods were allowed. Information on the following parameters was extracted and entered into a database: study design, type of intervention, number of patients, follow-up in months, cure rate, recurrence rate, intra/postoperative complications, and/or uni/bilateral, preventive/therapeutic, or concomitant procedures. Published papers from the years 1995 to 2011 were selected for analysis.

Abstract-Coexistence of multiple radio access technologies (RATs) is a promising paradigm to improve spectral efficiency. This letter presents a game-theoretic network selection scheme in a cognitive heterogeneous networking environment with timevarying channel availability. We formulate the network selection problem as a noncooperative game with secondary users (SUs) as the players, and show that the game is an ordinal potential game (OPG). A decentralized, stochastic learning-based algorithm is proposed where each SU's strategy progressively evolves toward the Nash equilibrium (NE) based on its own actionreward history, without the need to know actions in other SUs. The convergence properties of the proposed algorithm toward an NE point are theoretically and numerically verified. The proposed algorithm demonstrates good throughput and fairness performances in various network scenarios.
