PTNS for Overactive Bladder

Written by Nick Brook.

This video outlines overactive bladder (OAB) treatment with PTNS - percutaneous tibial nerve stimulation. OAB is a common and very problematic urological diagnosis that can severeley impact your quality of life. The treatment is easy, minimally invasive and avoids the side effects of tablet treatment.

Gleason 3+4 - active surveillance or surgery

Written by Nick Brook.

Can men with intermediate risk prostate cancer go on active surveillance?


Comparison of Pathological and Oncologic Outcomes of Favorable Risk Gleason Score 3 + 4 and Low Risk Gleason Score 6 Prostate Cancer: Considerations for Active Surveillance Journal of Urology, The, 2018-05-01, Volume 199, Issue 5, Pages 1188-1195

Some guidelines (eg. NCCN - National Comprehensive Cancer Network) suggest that men with small amounts of Gleason 4 (these are men with ISUP GG 2) on their biopsy can go onto active surveillance if other factors are suitable. But not much is known about long-term outcomes compared to that in men in the low risk Gleason score 3+3/Grade Group 1 group.

Prostate biopsy and inflammation

Written by Nick Brook.

Inflammation on a prostate biopsy may be linked to a lower prostate cancer risk in the future.


Inflammation on Prostate Needle Biopsy is Associated with Lower Prostate Cancer Risk: A Meta-Analysis. Journal of Urology, The, 2018-05-01, Volume 199, Issue 5, Pages 1174-1181

It is very common to find ‘inflammation’ on a prostate biopsy – 60-80% of biopsies may show this. It has long been debated whether inflammation is a risk factor for future prostate cancer and this has been unclear. This study was not a clinical study, but rather an examination of the medical literature for all studies reporting this finding.

The use of PSMA PET/CT for men who have a measurable PSA after radical prostatectomy

The use of PSMA PET/CT for men who have a measurable PSA after radical prostatectomy


PSMA after radical prostatectomy

“Efficacy, Predictive Factors, and Prediction Nomograms for 68Ga-labeled Prostate-specific Membrane Antigen–ligand Positron-emission Tomography/Computed Tomography in Early Biochemical Recurrent Prostate Cancer After Radical Prostatectomy”. European Urology Volume 73, Issue 5, Pages 656–661

In this study, PSMA PET/CT was used to examine men who had measurable PSA readings after radical prostatectomy. Recurrent disease was seen on imaging in 55% of men (74 out of 134) with very low (0.2–0.5 ng/ml) PSA and in 74% (102/138) of men with low (>0.5–1.0 ng/ml) PSA.

The ISUP Groups for prostate cancer

Written by Nick Brook.

Grade Group (ISUP Group) as the replacement for Gleason Score


The Gleason score has been ‘replaced’ by the ISUP Group for the scoring of the agressiveness of prostate cancer on biopsy or after radical prostatectomy. See below for a descritpion of the new scoring system:

  • GG 1(GS 3+3 = 6): cancers comprising only individual discrete and well-formed glands.

  • GG 2 (GS 3 + 4 = 7): cancers comprising predominantly discrete and well-formed glands with a lesser component of poorly formed/fused/glomeruloid/cribriform glands.

Active surveillance and prostate biopsies

Active surveillance for prostate cancer – how often do we see no cancer on a second biopsy?


Role of Surveillance Biopsy with No Cancer as a Prognostic Marker for Reclassification: Results from the Canary Prostate Active Surveillance Study. European Urology Volume 73, Issue 5, Pages 706–712

In this study, men on AS for prostate cancer were re-biopsied (surveillance biopsies) as per protocol. On first surveillance biopsy, 32% of men had no cancer, 43% had cancer that was the same ISUP group (Gleason score) as the first biopsy, and 25% had a change in the score on their biopsy.

Focal prostate cancer treatment may be coming soon

Written by Nick Brook.

Focal therapy - prostate cancer treatment for the near future?


What is focal therapy of the prostate?

In some ways, prostate cancer treatment has fallen behind other cancers. Although robotic surgery is a less invasive way of removing the prostate than an open cut, we are still not at the stage of being able to target cancer cells or groups of cells, and leave behind other non-cancerous cells in the prostate. This focused, or focal, treatment could have advantages in that important nearby structures are less at risk of damage compared to an operation to remove the prostate.

Robotic Fellowship in Europe

Advanced robotic training fellowship in Europe


Nick Brook will be in Belgium from April to Sept 2018

I will be undertaking a period of advanced robotic surgical training at Onze-Lieve-Vrouwziekenhuis Hospital, Aalst, Belgium from April to September 2018, under the mentorship of Prof Alex Mottrie.

The OLV is a high-volume robotic surgery hospital with a large department of Urology. The hospital has been undertaking robotic surgery since 2001 and is closely aligned to the OLV Vattikuti Robotic Surgery Institute (ORSI). The urology department produces a large volume of clinical data on outcomes for robotic surgery and regularly reports on new techniques.

Urologist in Adelaide - Prostate Biopsy

Robotic prostate biopsy

In January 2017, Nick Brook organised for a 6 month free trial of the Biobot robotic biopsy system at the Royal Adelaide Hospital. This is the first such system in South Australia, and was only the third in use in Australia.

The system uses a patient's MRI scan and fuses this with a real-time ultrasound of the prostate to enable targeting of suspicious areas in the prostate.


Increased accuracy of diagnosis leads to increased confidence that the correct treatment can be chosen.

Software controls the robotic arm, to ensure that the needles are placed in the correct position for biopsy

Focal therapy for prostate cancer

Written by Nick Brook.

Focal therapy for prostate cancer


Focal laser therapy may offer new options for men with prostate cancer

The idea of focal ablation (localised ‘killing off’) of cancers is not new – surgery for breast cancer was revolutionised years ago by the development of lumpectomy or wide local excision of tumours of the breast, rather than mastectomy (removal of the entire organ), in some settings. This idea has been slow to gain traction in prostate cancer, but may be a sensible option for tumours in the near future.

There are various options for focal ablation, and MRI-guided laser ablation shows a lot of promise in low and intermediate risk prostate cancer. Here, the very accurate application of heat energy from a laser is used to destroy prostate tumours. The position of the laser fibre in the prostate is guided by magnetic resonance imaging (MRI) and ultrasound using a fusion system. This is possible under sedation and local anaesthetic, as shown by a group at UCLA in the States. They first reported their findings in the Journal of Urology back in July 2016 (see here), and they followed up the study with a presentation at the American Urological Association Annual meeting in May 2017 (see here).
