Prostatic Adenomectomy by High Approach versus Millin: Our Results on a Series of 15 Cases

Abstract

Background: In 2023, conventional surgery for benign prostatic hyperplasia (BPH) is still used despite the introduction of minimally invasive techniques in the therapeutic arsenal. Objective: To present our results of Millin prostatic adenomectomy in a preliminary series of 15 cases. Patients and Methods: Cross-sectional study conducted at the Urology Department of the Bouaké University Hospital from January 2022 to January 2023. It involved 15 patients with benign prostatic hyperplasia (BPH) who had undergone high adenomectomy using the Millin technique. Results : During the study period, 15 cases of benign prostatic hyperplasia were treated surgically by high adenomectomy using the Millin technique. The mean age of the patients was 63.6 years, ranging from 53 to 78 years. Nine (9) patients were consulted for progressive complications of benign prostatic hyperplasia (BPH), i.e. 60% (n = 9). The mean IPSS score was 28 (20 to 35), and seven (7) patients had a comorbidity (46.44%). The digital rectal examination (DRE) was in favour of benign prostatic hypertrophy in all patients, and the mean weight of the prostate at DRE was 75 g, ranging from 55 g to 100 g. From a paraclinical point of view, prostatic ultrasound revealed a mean BPH weight of 82.7 g with extremes of 55 to 100 g. Post-micturition residue was greater than 150 ml in 60% (n = 9). The mean prostate-specific antigen (PSA) level was 3.8 ng/ml, ranging from 1.4 to 15 ng/ml. There was one case of severe anaemia with a haemoglobin level of 6 g/dl on haemogram, treated by blood transfusion. The cytobacteriological examination of the urine (ECBU) revealed five cases of E. coli infection, i.e. 33.33% (n = 5). Millin prostatic adenomectomy was performed under antibiotic prophylaxis at induction. All patients underwent locoregional anaesthesia. The mean weight of the adenoma was 80 g with extremes of 55 to 155 g. Blood loss was minimal at less than 100 ml, i.e. 86.6% (n = 13). The average operating time was 56.9 minutes, ranging from 45 to 75 minutes. The Retzius space was drained in an average of 2.75 days, with extremes of 2 to 4 days. The average duration of postoperative bladder catheterisation was 8.7 days, with extremes of 7 to 10 days. The average duration of bladder irrigation-washing was 3.6 days. The average hospital stay was 8.55 days, with extremes of 8 to 10 days. Morbidity was represented by Orchi-epididymitis (66%, n = 1) and mortality was 6.66% (n = 1). 6 months later, the 14 patients had good micturition comfort with an RPM of less than 10 ml. Anatomo-pathological examination of the adenomectomy specimen was in favour of an adenomyofibroma of the prostate with no stigma of malignancy. Conclusion: Prostatic adenomectomy using the Millin technique is rarely performed, but a look at the results shows that it is still the least morbid and fatal technique.
