Minimally invasive simple prostatectomy for a case of giant benign prostatic hyperplasia

Prostate artery embolization has long term efficacy for treatment of severe lower urinary tract symptoms from giant prostatic hyperplasia

Background

Patients with severe lower urinary tract symptoms (LUTS) from giant prostatic hyperplasia (GPH): prostate volume greater than 200 mL that do not respond to medical therapy may not be eligible for surgical treatments due to morbidities, technical challenges, and patient preference. This retrospective investigation examined the long-term efficacy and safety of prostatic arterial embolization (PAE) as a treatment option for severe LUTS due to GPH in a large patient cohort.

Methods

Of 529 patients who underwent PAE between January 2016 and January 2020, 72 patients had severe LUTS from GPH and were retrospectively evaluated. PAE was performed with two embolic agents in sequence: 100–250 μm particles followed by 2 mm and 3 mm coils. Clinical assessment was performed with international prostate symptoms score (IPSS), quality of life (QoL), peak flow rate (Qmax), post-void residual volume (PVR), and prostate specific antigen (PSA) measurements before and 12 months and 24 months after PAE. Prostate volume (PV) was measured by multiparametric magnetic resonance (MR) imaging before and 12 months and 24 months after PAE.

Results

Patients with severe LUTS from GPH experienced significant clinical improvements in IPSS, QoL, Qmax, PVR, PSA, and PV at 12 months and 24 months after PAE. Mean IPSS decreased from 26.5 to 18.0 (P < 0.01) to 10.5 (P < 0.01). Mean QoL decreased from 6.0 to 4.0 (P < 0.01) to 2.0 (P < 0.01). Mean Qmax increased from 8.0 to 14 mL/s (P < 0.01) to 18 mL/s (P < 0.01). Mean PVR decreased from 198.0 to 152.0 mL (P < 0.01) to 90 mL (P < 0.01). Mean PV decreased from 303.0 mL to 258.0 mL (P < 0.01) to 209.0 mL (P < 0.01). Mean PSA decreased from 11.2 ng/mL to 9.5 ng/mL (P < 0.05) to 7.9 ng/mL (P < 0.05). No major complications occurred.

Conclusions

PAE is a safe treatment with long term efficacy for severe LUTS from GPH. PAE may be a viable therapeutic option for patients with severe LUTS from GPH whom fail medical therapy and are not candidates for surgical treatments.

Giant prostatic hyperplasia and its causes

We present a  case of a  59-year-old male who was admitted to the emergency department with urinary retention, with a history of lower urinary tract symptoms, with the value of serum prostate specific antigen level of 100 ng/mL and an estimated prostate size of 800 mL, according to magnetic resonance imaging. A prostate  biopsy showed benign prostatic hyperplasia. Transvesical prostatectomy was performed, following additional procedure of transurethral resection of the prostate. To the best of our knowledge, this is the fourth highest prostate volume reported in medical literature. In this paper, we examine the factors that may have influenced the development of giant prostate hyperplasia.
