Effective intubation for percutaneous pyelolysis.

The pelvi-ureteric incision carried out during percutaneous pyelolysis has been intubated with a tapered 14-french catheter in 20 patients. This catheter provided both internal and external pelvic drainage and proved efficient in decompressing the upper ureter when drained externally. This catheter provided optimal conditions for pelvi-ureteric healing and allowed splintage of a sufficient diameter to enlarge the upper ureter and improve drainage from the obstructed renal pelvis.

The treatment of 100 consecutive patients with ureteral calculi in a British stone center.

Of all ureteral calculi 20 per cent will require removal. The use of extracorporeal shock wave lithotripsy has changed dramatically the treatment of ureteral stones requiring intervention. We reviewed 111 procedures for 108 stones in 100 consecutive patients. Primary techniques included extracorporeal shock wave lithotripsy after retrograde manipulation (63 cases), percutaneous nephrolithotomy alone (1) and after retrograde manipulation (3), ureteroscopic removal (29), cystoscopic removal (2) and open ureterolithotomy (2). These techniques and the results are discussed. Of the patients 11 required a secondary procedure, including extracorporeal shock wave lithotripsy in 3, ureterorenoscopy for failed extracorporeal shock wave lithotripsy in 2, an open operation for complications of ureterorenoscopy in 2 and correction of associated stricture in 2. All patients ultimately were free of stones. Our experience with in situ extracorporeal shock wave lithotripsy is described. An open operation was done only when less invasive forms of treatment failed or electively to correct an associated anatomical abnormality.

The integrated cystoscope: an alternative to conventional and fibreoptic cystoscopy.

This report describes a new integrated rigid cystoscope which has been designed for diagnostic and therapeutic cystoscopy under local anaesthesia. The small external diameter (17.5 F) and large instrument channel permit maximum irrigant flow and operating potential whilst causing minimum discomfort to the patient. We believe this instrument to be a practical alternative to conventional cystoscopes, including the fibreoptic cystoscope.

The complications of extracorporeal shockwave lithotripsy: management and prevention.

Extracorporeal shockwave lithotripsy has been shown to be a safe and effective method of treating most upper urinary tract stones. Major complications, although few, include haemorrhage, septicaemia, "Steinstrasse" formation and cardiac arrhythmias. The experience from 600 consecutive cases is reviewed and methods of prevention are discussed.

Combination of percutaneous surgery and extracorporeal shockwave lithotripsy for the treatment of large renal calculi.

Open surgery for large or complex renal calculi may be difficult, particularly in patients with recurrent stones, and may require special operative techniques to preserve renal function. With the advent of percutaneous nephrolithotripsy (PCNL) and extracorporeal shockwave lithotripsy (ESWL) new approaches are now available for the treatment of these difficult cases. A review of 67 patients who presented between November 1984 and May 1986 has shown that it was possible to clear large stones in 71% of patients using a combination of PCNL and ESWL. There was no mortality; the morbidity for both procedures was low and was less than when either procedure was used alone for the treatment of complex stones.

The development and application of a new surgical device--the Endoscopic Liquidiser and Surgical Aspirator (ELSA).

Modern surgery is looking for ways to carry out procedures which limit unnecessary damage to the patient. This means, in practice, using smaller incisions and special tools. An instrument for removing tissue through a small cross-section has been developed. It is suitable for both endoscopy and laparoscopy. The instrument and its development is described, and its performance evaluated in vitro and for a range of clinical procedures. Experiments aimed at uncovering the mechanism of cutting are discussed as to their relevance for practical instrument development.
