the overall rate of atrial pacing lead dislodgement is estimated to be about 3%. these leads are generally repositioned via a second operation through opening the pacemaker pocket. some operators have introduced percutaneous techniques using snare system or deflectable catheters for this purpose. in this article we present our experience with five cases of percutaneous lead repositioning. three...

conclusions aki is common in urology patients. the underlying aetiologies of aki in this group may explain a lower overall mortality, although increasing aki severity remains a marker of patients at higher risk of poor outcomes. the low rate of renal recovery suggests that urology patients who sustain aki are exposed to a significant risk of ckd and its attendant consequences for long term heal...

We evaluate two coordinate transformation techniques in combination with grid stretching for pricing basket options in a sparse grid setting. The sparse grid technique is a basic technique for solving a high-dimensional partial differential equation. By creating a small hypercube sub-grid in the ‘composite’ sparse grid we can also determine hedge parameters accurately. We evaluate these techniq...

The pre-transplantation goal of the urologist is the optimization of urinary tract condition. Therefore, urologic surgery may be needed before or after renal transplantation. We analyzed the results of urologic surgery performed because of de novo urologic diseases. Between January 1986 and January 2001, 281 patients underwent renal transplantation, and 23 urologic surgical procedures were perf...

I show that P(2, 3) has an embedding P(2, 3) ∼= Γ ⊂ P(4, 5, 6, 9) whose image Γ is contained in a quasismooth K3 hypersurface X24 ⊂ P(4, 5, 6, 9). The pair Γ ⊂ X24 unprojects to the codimension 4 K3 surface Y ⊂ P(4, 5, 5, 6, 7, 8, 9) with Basket = [ 1 2 (1, 1), 1 5 (1, 4), 1 5 (2, 3), 1 9 (4, 5) ]. Numerator = 1− t − t − 2t − 2t − 2t − t + t + 2t + 3t + 4t + 3t + · · · (Altınok4(111) in the Mag...

D iabetes and urologic diseases are very common health problems that markedly increase in prevalence and incidence with advancing age (1–3). Diabetes is associated with an earlier onset and increased severity of urologic diseases, resulting in costly and debilitating urologic complications. Urologic complications, including bladder dysfunction, sexual and erectile dysfunction, as well as urinar...

A 59-year-old woman was treated with ERCP, ES, and biliary plastic stent, for large and multiple common bile duct stones. During a second ERCP basket extraction was impacted with a round entrapped stone. The basket handle was cut off; a metal sheath of extraendoscopic lithotriptor was advanced over the basket. The mechanical lithotripsy was complicated with basket traction wires fracturing, wit...

Background: The field of urology has undergone unprecedented advances in the past decades and the developments in modern urology which are practiced today have been made possible by the remarkable strides surrounding surgery made in the mid and late 20th century. Objectives: The study was aimed at assessing the extent of urologic conditions and the treatment modalities in the study area. Method...
