Although rarely mentioned in the literature a Candida urinary tract infection associated with hemiacidrin renal irrigation is not unexpected.'i, 6 Patients undergoing this therapy receive long-term broad-spectrum antibiotics, which predispose the urinary tract to colonization yeast. Although usually of low virulence in nonimmunosuppressed patients Candida can cause morbidity and even renal loss in patients having renal irrigation.7 Treatment of these Candida infections has proved to be simple and safe. The same precautions used during hemiacidrin

with the nephrostomy providing drainage of the effluent. Two of our patients who had extravasation of irrigant also had chemical cystitis. No patient in our series exhibited hypermagnesemia or deteriorated renal function. Because hypermagnesemia has been reported in a uremic patient 10 the serum magnesium of patients with impaired renal function must be monitored closely. None of the complications listed herein proved to be lifethreatening. However, they did prolong the hospitalization of these patients and this can be a heavy burden for an otherwise healthy patient and can test the patience and dedication of the professional staff. To obviate the need for lengthy irrigation every effort must be made to extract all stone fragments at the operation. Despite the best efforts, however, total stone removal is not always possible. Preoperatively, the patient and family should be fully counseled concerning the possibility of postoperative renal irrigation and the substantial investment of time that may be required. CONCLUSION
Postoperative hemiacidrin renal irrigation for retained struvite stone fragments can be accomplished effectively and safely provided sterile urine and a low pressure perfusion system are maintained. The complications that do occur can be managed safely. Such safe management requires considerable time, effort and determination on the part of the patient, the physician and the nursing staff. REFERENCES 1. Fa~, B., Rossier, A. B., Yalla, S. and Berg, S.: The role of hemia-
perfusion should be used with amphotericin B. Sterile water is used to avoid the precipitation of the fungicide that occurs with sodium chloride. The chills, fever, vomiting and headache frequently encountered with the intravenous administration of amphotericin B have not occurred with renal perfusion of the drug. Renal function has remained unchanged. The extravasation of irrigant encountered in these cases probably results from the changes that the uroepithelium undergoes when exposed to hemiacidrin. Ulceration may occur8 • 9 and impaired healing of suture lines also is likely. Such weakened areas may leak when exposed to even modest increases in pressure caused by edema of the proximal ureter or by the passage of sandy calculous debris. Attenuated areas that easily rupture explain why the leakage can occur at any time during the course of the irrigation and why 3 of our patients did not have pain before the leakage. Whatever the cause it is unwise to remove the drains placed at the operation until the irrigation has been completed. Chemical cystitis commonly is associated with hemiacidrin renal irrigation and occurs in men and women. Treatment includes insertion of a Foley urethral catheter, cessation of the irrigation until the symptoms have subsided or irrigation with saline until the patient is asymptomatic. Particularly severe cases may necessitate irrigation through a ureteral catheter
