Objective: To study the effect of age, type of surgery and comorbidities (cardiovascular diseases, chronic lung diseases, diabetes mellitus and renal impairment) on the peri-operative complications and mortality of prostatectomy.
Patients and methods: A series of 236 consecutive patients who underwent prostatectomy (171 by transurethral resection, TUR, and 65 by open procedure) were reviewed. Ninety patients at risk with one or more of the comorbidities were grouped together and compared with the remaining 146 fit patients. Also, 148 patients aged < or = 70 years were compared with 88 patients aged > 70 years. The peri-operative morbidity variables compared were haemorrhage, > or = 3 units of blood transfusion, bacteriuria, orchitis, pyrexia, uraemia and bed-stay.
Results: Mean post-operative bed-stay for patients at risk was significantly longer than that for fit patients (12 +/- 7 and 9.7 +/- 6 days, respectively). Mortality and the other morbidity variables, apart from post-operative bacteriuria which was more frequent in diabetics, were not significantly different between the groups. Similarly, comparing age groups revealed no significant differences. However, open surgery was associated with more haemorrhage, blood transfusion, post-operative pyrexia and a longer bed-stay.
Conclusion: The comorbidities studied and age did not significantly influence the complications and mortality of prostatectomy. However, comorbidities prolonged post-operative bed-stay. Open surgery was associated with more bleeding and pyrexia and a longer bed-stay than TUR.
