Prostatic obstruction [ 1] is a common condition with a variety of causes. Benign prostatic hyperplasia (BPH) is the most common cause, [ 2] but ...
88.97. MeSH. D049448. OPS-301 code. 3-843. [ edit on Wikidata] Magnetic resonance cholangiopancreatography ( MRCP) is a medical imaging technique. It uses magnetic resonance imaging to visualize the biliary and pancreatic ducts non-invasively. This procedure can be used to determine whether gallstones are lodged in any of the ducts surrounding ...
22.1 million (2015) [ 5] Deaths. 16,100 (2015) [ 6] Kidney stone disease, also known as renal calculus disease, nephrolithiasis or urolithiasis, is a crystallopathy where a solid piece of material ( renal calculus) develops in the urinary tract. [ 2] Renal calculi typically form in the kidney and leave the body in the urine stream. [ 2]
This has the advantage of showing whether there is any obstruction of flow of urine causing hydronephrosis as well as demonstrating the function of the other kidney. Many stones are not visible on plain X-ray or IVU but 99% of stones are visible on CT and therefore CT is becoming a common choice of initial investigation. CT is not used, however ...
Pyelogram (or pyelography or urography) is a form of imaging of the renal pelvis and ureter. [ 1] Types include: Intravenous pyelogram – In which a contrast solution is introduced through a vein into the circulatory system. Retrograde pyelogram – Any pyelogram in which contrast medium is introduced from the lower urinary tract and flows ...
Percutaneous hepatic cholangiogram. ICD-9-CM. 87.51. OPS-301 code. 3-13c .1. [ edit on Wikidata] Percutaneous transhepatic cholangiography, percutaneous hepatic cholangiogram ( PTHC) is a radiological technique used to visualize the anatomy of the biliary tract.

Complications. Acute kidney injury. Renal colic, also known as ureteric colic, is a type of abdominal pain commonly caused by obstruction of ureter from dislodged kidney stones. The most frequent site of obstruction is the vesico-ureteric junction (VUJ), the narrowest point of the upper urinary tract.
