Active clinical trials for "Urologic Diseases"

The purpose of this study is to determine whether periprocedural administration of folic acid is effective in the prevention of contrast induced nephropathy in patients undergoing coronary CTA/angiography/angioplasty.

This is a Phase 2b, prospective, open-label study designed to evaluate the safety, tolerability, PK, and PD of FAST PV and mGFR Technology in healthy subjects and patients with varying degrees of renal impairment.

This phase II randomized (1:1) controlled trial will examine the effects of remote ischemic conditioning (RIC) on the outcomes of major abdominal surgery. One hundred subjects will be enrolled at a single institution - University Hospital - Newark. The study population are patients undergoing major abdominal surgery (anticipated to be >/= 2 hrs long with a hospital stay >/= 2 days). Subjects in the treatment group will receive lower limb ischemic conditioning at 3 different time points: before surgery, POD 1 and POD 2. The primary outcome is the 30-day comprehensive complications index (CCI). Key secondary outcomes are changes in systemic inflammatory markers in peripheral blood and 30-day mortality.

The Objective is to determine if renal hypothermia during open partial nephrectomy results in improved post-operative renal function compared to warm ischemia. Primary Aim is to determine the effect of hypothermia on preservation of overall renal function compared to no hypothermia in patients who require hilar vessel clamping during open partial nephrectomy for a renal tumor. Hypothesis: Hypothermia will result in improved post-operative preservation of overall renal function. Secondary Aim is to determine the effect of hypothermia on preservation of affected renal function (kidney with the tumor) compared to no hypothermia in patients who require hilar vessel clamping during open partial nephrectomy for a renal tumor. Hypothesis: Hypothermia will result in improved post-operative preservation of affected renal function.

The purpose of this study is to determine what causes some people to become sick, and others not, when they are infected with the parasite Schistosoma haematobium, also known as Bilharzia. This is an infection of the urinary tract blood vessels and can cause serious disease. Approximately 4400 adults and children of any age will participate in this study. They must be residents of the Msambweni Area, Kwale District, Coast Province, Kenya, where infection with S. haematobium parasites are common. To find out if people are infected, they will first provide 1 or more urine samples for a microscope examination to detect if the S. haematobium parasites are present in the body. Volunteers then will be examined by ultrasound to see if they have kidney or bladder disease. (Ultrasound examination is the use of a non-painful machine that uses sound waves to examine the condition of the internal organs.) Treatment with the drug praziquantel will be offered if S. haematobium infection is found.

Urological surgery patients will have their blood glucose measured before, during, and after surgery. Blood glucose will be measured using a continuous glucose monitor (CGM) device. We hypothesize the presence of a hyperglycemic state towards the end of surgery due to increased metabolic demand.

A study to understand the impact of Betmiga® on patients quality of life, satisfaction with treatment, how long patients remain on treatment, patterns of healthcare resource utilisation, and safety as prescribed by the physicians in routine clinical practice.

Significant differences exist among various dermatome maps. In addition, there were no anatomical landmarks to evaluate the dermatome at the back. The investigators aim to map the sensory innervations of lower thoracic nerves and find the dorsal landmarks to evaluate sensory innervations by epidural block. Patients undergoing urological surgery will receive epidural block. Fifty patients with superior border of complete sensory loss to ice from T9 to T12 (anterior median line) will be included in this study. The sensory loss to ice will be evaluated at midclavicular line, anterior axillary line, posterior axillary line, scapular line and posterior median line. The level of vertebrae will be identified and marked by ultrasound. The superior border of complete sensory loss to ice from anterior median line to posterior median line will be recorded for every patient. The dermatome map of T9 to T12 will be drawn. The landmarks of sensory innervations at posterior median line will be established using vertebrae.

The role of bowel bladder disorder, or BBD, has been highlighted as a major player in vesicoureteral reflux and urinary tract infection (UTI). However, the diagnosis of BBD are still conceptual and subjective, because of the diagnosis of constipation, main pathophysiology in BBD has not been established well.

The investigator intends to review retrospective de-identified data of patients who have had Open, Laparoscopic, Ureteroscopic or Percutaneous Urologic Surgery.
