Urology, pathology Papillary urothelial neoplasm of low malignant potential ( PUNLMP ) is an exophytic (outward growing), (microscopically) nipple-shaped (or papillary) pre-malignant growth of the lining of the upper genitourinary tract (the urothelium ), which includes the renal pelvis , ureters , urinary bladder and part of the urethra .
The frozen section procedure as practiced today in medical laboratories is based on the description by Dr Louis B. Wilson in 1905. Wilson developed the technique from earlier reports at the request of Dr William Mayo, surgeon and one of the founders of the Mayo Clinic [3] Earlier reports by Dr Thomas S. Cullen at Johns Hopkins Hospital in Baltimore also involved frozen section, but only after ...
Gross examination of a kidney (right of image) with a renal oncocytoma (left of image).. Gross processing, "grossing" or "gross pathology" is the process by which pathology specimens undergo examination with the bare eye to obtain diagnostic information, as well as cutting and tissue sampling in order to prepare material for subsequent microscopic examination.
Some patients are given mitomycin into the bladder either as a one-off dose in the immediate post-operative period (within 24 hrs) or a few weeks after the surgery as a six dose regimen. Localized/early transitional cell carcinomas can also be treated with infusions of Bacille Calmette–Guérin into the bladder. These are given weekly for ...
The resection is an attempt to remove a cancer tumor so that no portion of the malignant growth extends past the edges or margin of the removed tumor and surrounding tissue. These are retained after the surgery and examined microscopically by a pathologist to see if the margin is indeed free from tumor cells (called "negative"). If cancerous ...
Postcholecystectomy syndrome (PCS) describes the presence of abdominal symptoms after a cholecystectomy (gallbladder removal). Symptoms occur in about 5 to 40 percent of patients who undergo cholecystectomy, [1] and can be transient, persistent or lifelong. [2] [3] The chronic condition is diagnosed in approximately 10% of postcholecystectomy ...
