A case of urethral caruncle, composed exclusively of mucin-secreting colonic-type glands and believed to be the first on record, is described. The lesion presented clinically as an ordinary caruncle and was treated by local excision. The histogenesis of the lesion is discussed, and its probable origin from an intraurethral cloacogenic colonic gland rest is proposed.
Computed tomography can aid in the distinction of calculi from both tumors and clots in the urinary tract. Its availability, simplicity of interpretation, and noninvasiveness establish it as an important diagnostic modality in selected cases when calculus is in the differential diagnosis of upper urinary tract filling defects.

A case of a benign renal cyst, which was filled with blood under pressure and causing acute flank pain, is presented. The pain was relieved after cyst puncture and aspiration. Although benign hemorrhagic renal cysts are well recognized, this is the first report of a benign renal cyst filled with blood under pressure.

Percutaneous nephropyelostomy using the posterolateral approach was employed together with antibiotics and other supportive therapy as the initial step in the treatment of acute pyohydronephrosis, with gratifying results. Percutaneous nephropyelostomy is recommended as the procedure of choice for this specific clinical emergency.
A study was undertaken to assess the applicability of the slit-scan technique to automated prescreening of urinary tract cytology. Cells from voided and catheterized urines were stained with acridine orange and measured on a static cell slit-scan cytofluorometer. Analysis of data from the specimens indicates that nuclear fluorescence alone appears adequate for recognition of abnormal specimens. Remaining problems in the automation of urinary tract cytology prescreening are discussed.
Experience with 207 cases of blunt renal trauma is reviewed. We have found that renal scans and selective renal arteriography are the most informative diagnostic tests. However, in a small community setting we suggest use of an infusion urogram and a retrograde pyelogram. Our accuracy rates with these 4 diagnostic tests are listed and selected cases are illustrated. We believe that if exploration is warranted, kidney salvage rates will be improved because of an accurate assessment of the extent of renal injury.
