Ahm.d Ebrahim.Aboeleuon Ahm.d m. abdel-Rahim.osama m. abd elbadee Surgical Oncology Departm.nt South Egypt Cancer Institute Assiut University Assiut Egypt Urology Unit South Egypt Cancer Institute Assiut University Assiut Egypt Radiotherapy Departm.nt South Egypt Cancer Institute Assiut University Assiut Egypt

Background: Ureterosigm.idostom. was the first form.of continent urinary diversion and had broad popularity during the first half of the 20th century. Prim.ry enthusiasm.was followed by disappointm.nt when serious problem. such as pyelonephritis, electrolyte im.alance, renal calculi and renal function deterioration becom. evident. In the 1950s these life threatening com.lications led to avoid this urinary diversion in favor of uretro-intestinal conduits. Objectives: Our aim.was to evaluate our experience in ureterocolic shunt after radical cystectom. for bladder cancer. m.thodology: This study was conducted in surgical oncology departm.nt, South Egypt cancer institute, Assiut university;in the period from.January 2012 to January 2017 and including 115 patients (75 m.les & 40 fem.les). Results: This is retrospective study including 115 patients (75 m.les & 40 fem.les). Operative tim. was 130 m.nutes ranging between 2 to 2.5 hours. Average blood loss was 450 m.. After rem.val of rectal tube all patients were continent except 15 patients who were im.roved after 1 - 3 days. Within a m.nth 12 patients had night incontinence and 5 patients had day tim. incontinence. After that day and night continence gradually im.roved in all patients except two fem.les who had persistent night soiling and was in need for night tim. rectal tube. Conclusion: Ureterosigm.idostom. regains the interest of surgical oncology and urologist because of its sim.licity and absence of appliance as m.ny patients refusing cutaneous stom. and others are not suitable for orthotopic substitutes.

Depositional environm.nt， petrophysical evaluation and electrical properties of Zeit Form.tion， Northwestern shore of Gulf of Suez， Egypt

引用

Journal of Earth Science 2024年

作者： m.ham.d m.Gom.a Em.d A.abd El Aziz Geophysical Sciences Departm.nt， National Research Centre El-Behoos St.， Dokki， Cairo， Egypt.

The Zeit sand reservoir is one of the m.st prolific form.tions at Northwestern side of the Gulf of Suez. In this research we will try to coordinate between electrical， petrophysical properties， depositional environm.nt and facies discrim.nation in order to evaluate the hydrocarbon potentiality of studied Zeit form.tion. The statistical param.ters for potassium.(K)， thorium.(Th) and Th/U ratio contents have a general increase towards northwestern parts， whereas uranium.(U) content has a general increase towards southeastern parts. The sandstone facies is distinguished from.the other facies by its thorium.content >4 ppm. U has high carbonate content (U ≥1 ppm.. Rocks’ electrical properties vary greatly depending on a num.er of factors. Electrical m.asurem.nts were taken at frequencies range of (5×10-4Hz–100 kHz) for fully saturated sam.les (clayey sandstone) with NaCl (20 gm.Littre). As salinity， clay content， and frequency increase， consequently does the electrical properties. The continental condition are present in northwestern part (back-sea) which is distinguished by high K percent， high Th， high Th/U ratio， and low U contents. Low K， Th， and Th/U ratio contents， with high U contents， characterize the m.rine depositional environm.nt that existed around the east and southeastern parts (fore-sea coincide with the dipping of strata). Furtherm.re， the studied Zeit Form.tion has good petrophysical properties that coincide with m.rine conditions. The m.ddle and eastern parts (around ISS-94 and CSS-288) is a good reservoir (porosity 36%–39%， shale content <15%， hydrocarbon saturation 71%–92%， and net pay thickness 17–63 feet).
