Is a "retained fundus" seen on postoperative upper gastrointestinal series after laparoscopic sleeve gastrectomy predictive of inferior weight loss?

Background: Postoperative upper gastrointestinal series (UGI) has never been shown to be effective in ruling out leaks or obstruction after gastric bypass or sleeve gastrectomy. In sleeve gastrectomies, UGI will define the shape of the sleeve and rule out a retained fundus that was not optimally excised during surgery.

Objectives: We aimed to investigate the impact of a "retained fundus" on weight loss to determine whether UGIs can be used to gauge success of the operation and predict outcome.

Analgesic Effects and Safety of Desmopressin, Tramadol and Indomethacin in Patients with Acute Renal Colic; A Randomized Clinical Trial.

Objective: To compare the efficacy of desmopressin (DDAVP), tramadol and indomethacin on pain intensity of patients with acute renal colic caused by urolithiasis.

Methods: This prospective, randomized clinical trial was conducted between July 2005 and July 2006 including 120 patients (70 men and 50 women, mean age 38.2±5.

Patient outcomes and surgical complications in coccidioidomycosis-related hydrocephalus: an institutional review.

Objectives: Coccidioidomycosis is a common fungal infection in the southwestern US. Hydrocephalus is a serious complication of cranial coccidioidomycosis, and the surgical management of coccidioidomycosis-related hydrocephalus has unique challenges. The authors reviewed their institutional experience with hydrocephalus in the setting of coccidioidomycosis.

Role of viruses in renal cell carcinoma.

To determine whether viral infections are related to renal cell carcinoma (RCC), we studied 49 patients with RCC (29 patients were males with age ranging from 30 to 81 years and a mean of 57.5 years; 20 patients were females with age ranging from 36 to 70 years with a mean of 58.4 years) and 16 non-neoplastic kidney patients as controls.

Laparoscopic nephrectomy for nonfunctioning kidneys is feasible after previous ipsilateral renal surgery: a prospective cohort trial.

Purpose: Previous renal surgery is a relative contraindication to laparoscopic nephrectomy because adhesion formation makes surgical dissection difficult. We determined whether previous surgery at the same anatomical site would affected the surgical outcome in patients who underwent transperitoneal laparoscopic nephrectomy.

Materials And Methods: During the study period 79 consecutive patients who underwent transperitoneal laparoscopic nephrectomy were evaluated prospectively.

Comparison of the protective effects of papaverine, lidocaine and verapamil on the sperm quality of the testis after induced torsion-detorsion in rats.

Objective: Spermatic cord torsion is a true urological emergency. Significant subfertility exists in patients following unilateral testicular torsion. Several studies have tested several agents such as vasodilators and antioxidants to inhibit or temper testicular damage.

Is early reimaging CT scan necessary in patients with grades III and IV renal trauma under conservative treatment?

Background: To clarify the role of reimaging computer tomography (CT) scan in the management of patients with grades III and IV renal trauma under conservative treatment.

Methods: In a cross-sectional study, 94 patients with grades III and IV renal trauma from 405 patients with renal injury were selected for nonoperative management. On arrival according to related indications, CT scan of the kidney was performed for all patients and repeated CT scans were done 36 hours and 5 days later.

Urethral catheter traction reduces bleeding compared with suturing of prostatic vesical junction during suprapubic prostatectomy: a randomized clinical trial study.

Objectives: To determine whether catheter traction during suprapubic prostatectomy can be beneficial in reducing intraoperative and postoperative bleeding.

Methods: A total of 156 patients with lower urinary tract symptoms who had indications for open prostatectomy were enrolled in the study from September 2004 to January 2006. Of the patients, 78 underwent open prostatectomy with suturing at the prostatic vesical junction (group 1) and 78 were treated with urethral catheter traction to control bleeding (group 2).

Ultrasonography-guided percutaneous nephrolithotomy.

Purpose: To evaluate the safety and efficacy of ultrasound-guided percutaneous nephrolithotomy (PCNL).

Patients And Methods: Between August 2003 and December 2007, 47 patients were treated, 29 men and 18 women, with a mean age of 33.4 years (range 21-67 yrs) and a mean stone size of 31.

Age specific reference levels of serum prostate-specific antigen, prostate volume and prostate specific antigen density in healthy Iranian men.

Background: It is relevant to highlight that there is not a precise and perfect report on either 95 percentile value (upper limit of normal range) or on appropriate reference intervals for serum PSA in Iranian population.

Objective: To determine age-specific reference ranges for serum prostate-specific antigen (PSA) concentration and PSA density (PSAD) and prostate volumes in a population of healthy Iranian men.

Methods: Nine-hundred and thirteen healthy Iranian men, aged 50-79 years, underwent a detailed clinical evaluation including a digital rectal examination, a serum PSA determination (DRE) and transrectal ultrasound (TRUS).
