Purpose: This study investigates the efficacy and safety of Rezǔm water vapor in the management of Malaysian men with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH).

Material and methods: A total of 60 men with symptoms of moderate to severe BPH were enrolled in pilot studies at Hospital Sultan Abdul Aziz Shah, Universiti Putra Malaysia. All patients were treated with transurethral delivery of water vapor. International Prostate Symptom Score (IPSS), quality of life (QoL), peak urinary flow (Qmax), postvoid residual, and International Index of Erectile Function (IIEF-5) were evaluated at 1 week and 1, 3, and 6 months post-treatment. Safety was also assessed.

Results and discussion: The mean age of our study population was 64.57 ± 9.37 years old with mean prostate volume of 59.98 ± 22.06 cc. Our findings revealed statistically significant improvements throughout the 6 months of follow-up for IPSS score (17.45 ± 6.10 score to 7.53 ± 4.28), the QoL scores (3.52 ± 1.19 to 1.53 ± 0.70) and the urinary flow rate, Qmax (9.74 ± 3.39 mL/s to 17.40 ± 5.92 mL/s). There was no significant difference (p>0.05) was observed in sexual function (IIEF-5 scores) when compared to preoperatively. No adverse events (AEs) related to endoscopic instrumentations were observed. Two cases of urinary retention were classified as procedure-related AE.

Conclusion: The Rezǔm water vapor therapy is safe and provides effective relief of symptoms and it should be considered as one of the treatment options in patients with LUTs associated with BPH especially for patients who are keen to preserve sexual function as part of the added benefit in this treatment modality.

ANGIOEMBOLISATION OF CREMASTERIC ARTERY FOR SCROTAL HAEMATOMA FOLLOWING HERNIAL REPAIR

Dr Z — Sun, 31 Mar 2024 00:00:00 +0000

Cremasteric artery is a branch of inferior epigastric artery supplying the cremaster muscle and coverings of the cord. The possible consequence of injury to this artery is scrotal haematoma. We present a case of haemorrhage from unexpected cresmastric artery injury post-hernioplasty treated with angioembolisation. To the best of our knowledge, this has not been reported in literature.

A 66-year-old gentleman with left indirect inguinal hernia underwent a left inguinal hernioplasty in our institution with no immediate complications. However he presented to the emergency department the day after the procedure with complaints of rapidly worsening painful left scrotal swelling accompanied with symptoms of intestinal obstruction. Emergency laparotomy and re-do left hernioplasty was performed, revealing a strangulated inguinoscrotal hernia. Post-operatively, there was non-resolving scrotal swelling with a drop in the haemoglobin level; from 11.9g/dl to 8.5g/dl requiring packed cell transfusion. CT angiogram revealed active contrast extravasation from the left cremasteric artery. Angiographic run confirmed the finding and the left cresmatric artery was superselectively cannulated with a 1.9Fr microcatheter and embolization done with 0.5mm microcoil. Ultrasound scan 24-hour post-procedure showed patent proximal vessel. Clinically there was a reduction of the left scrotal swelling and the haemoglobin remained stable.

Cremasteric artery courses laterally deep into the fascia transversalis entering the cord deep to the internal spermatic fascia to supply the cremaster muscle and coverings of the cord. This course renders the artery to be prone for injury during procedure such as hernioplasty; one of the possible consequences is scrotal haematoma. This artery is usually small in caliber and its identification is important for efficient and effective treatment.

Angioembolisation is able to treat this injury with superior precision owing to its ability for localization and selective cannulation of the offending vessel.
