In-bath filming during extracorporeal shock wave lithotripsy.

Extracorporeal shock wave lithotripsy (ESWL) is now the preferred method for treating most renal calculi. We designed a cassette and grid holder and a technique for filming in the water bath. The excellent film quality permits initial localization of small or faint calculi and confirmation of satisfactory fragmentation during ESWL. The technique facilitates patient treatment and throughput and should reduce the repeat treatment rate.

Upper ureteral calculi: extraction via percutaneous nephrostomy.

Symptomatic calculi in the upper ureter are usually removed using surgical and endoscopic techniques. Extraction via percutaneous nephrostomy was successful in 35 of 37 patients using sequentially the techniques of retrograde catheter push, basket sheath exchange, and steerable loop-snare. In 12 patients, the calculus was dislodged into the renal pelvis by the retrograde ureteral catheter; extraction was then easily done. Stone basket retrieval was used for an additional 17 patients. A steerable loop-snare was necessary in six other patients when basket retrieval failed.

Balloon catheter angioplasty. Which patients with renovascular hypertension are candidates?

Balloon catheter dilation of a stenotic renal artery can cure or enable easy medical control of renovascular hypertension when vessel narrowing is caused by fibromuscular dysplasia or an isolated atherosclerotic plaque in the main renal artery. This procedure is recommended instead of surgery for these lesions when primary medical management of hypertension fails.

Ultrasonic renal lithotripsy. Single-stage percutaneous technique and adjuvant radiological procedures.

Single-stage percutaneous ultrasonic disintegration and removal of renal calculi was attempted in 67 patients (80 calculi) and proved successful in 65 (97%). Extraction was achieved during the initial session in 52 patients (78%) and required either an adjuvant radiological procedure or repeat nephroscopy in 13. Single-stage removal combines the skills of the radiologist and urologist and is successful in the majority of cases.

Celiac plexus block: a roentgenographic, anatomic study of technique and spread of solution in patients and corpses.

Techniques for blocking the celiac plexus were evaluated by conventional posteroanterior and lateral x-rays and computed tomography (CT) in 20 patients with intractable pain due to carcinoma of the pancreas and by determining spread of injected dye at the time of autopsy in three corpses. The results showed that (a) the site for insertion of the needles should not be more than 7.5 cm lateral to the spinous process of a lumbar vertebra, (b) needles should be placed bilaterally, (c) the depth to which needles are inserted is greater than previously recommended, and (d) at least 25 ml of solution should be injected through each needle.

A simple hospital radiology information system.

The film jackets of hospitalized patients are filed in a consultation room according to hospital room and bed number. A single file clerk handles inpatient activity, which includes the expedited preparation of radiographs for reporting, as well as the filing and delivery of the reports to other departments of the 321-bed hospital. Clinicians have easy, immediate access to the radiographs, the consultation of a radiologist, and the report. This results in the meaningful transfer of information. The system requires minimal space and no investment in automated viewers or additional clerical personnel. Acceptance by the clinicians, the staff, and the radiologists has been enthusiastic.

Needle tract seeding following aspiration of renal cell carcinoma.

A case of tumor implantation along the needle tract 20 months after needle aspiration of a renal cell carcinoma is reported. This rare but possible complication of needle aspiration should not discourage its use in the evaluation of renal mass lesions. Needle aspiration should be reserved for those patients in whom the clinical findings, roentgenograms and sonography indicate a benign process (that is to confirm that the mass is benign).

A new method for percutaneous nephrostomy.

A new method of percutaneous nephrostomy using techniques to place a No. 12 French balloon catheter in the renal collecting system is described. Case reports demonstrate tumor palliation and temporary drainage to improve the very ill prior to definitive surgery. A translumbar aortogram catheter is placed lateral to paraspinous muscles and Dotter vascular dilators are used to allow insertion of the large balloon catheter.

Arteriovenous fistula of the renal vessels: Surgical management.

The fifth case of arteriovenous fistula following nephrectomy for tuberculosis is presented. It is important to consider an arteriovenous communication in cases of unexplained congestive heart failure, particularly when blood pressure findings suggest arteriovenous shunting. The importance of the history of nephrectomy and findings of a loud bruit upon auscultation of the abdomen is evident. Diagnosis is established by selective renal angiography. The preferred treatment is complete excision of the fistulous communication.
