Australian surgical revision rate for benign prostatic obstruction.

OBJECTIVE: To evaluate the rate of revision surgery following commonly performed procedures for benign prostatic hyperplasia (BPH) is hyperplasia of both glandular and stromal components of prostate especially in periurethral transitional gland, using real-world data from Medicare Australia. METHODS: Prospection is a Healthcare Data Analytics firm that has negotiated access with the Medicare Benefits Schedule (MBS) to provide longitudinal data on the use of specific procedural item codes. We identified patients over the age of 40 years who had undergone primary transurethral resection of the prostate (TURP), transurethral incision of the prostate (TUIP) or photoselective vaporization of the prostate (PVP) between 2005 and 2010 using MBS item numbers 37203, 37207 and 36854, respectively. Using longitudinal MBS data, primary outcomes included need for revision surgery at 5-years follow-up (2015). The release of these data was approved by Medicare Australia upon application. Data analysis was conducted using chi-squared tests and statistical significance was defined at P < 0.05. RESULTS: The distribution of primary surgical procedures performed between 2005 and 2010 was: TURP 5579 (90%), TUIP 345 (6%) and PVP 258 (4%). TURP was also the most prevalent procedure for treatment of lower urinary tract symptoms in men with BPH requiring revision surgery (75%). At 5-year follow-up the rate of revision surgery for TURP (573/5579), TUIP (47/345) and PVP (30/258) was 10.3%, 13.6% and 11.6%, respectively. The difference was not statistically significant (P = 0.12). There was no significant change (P = 0.59) observed over the years in number of men requiring revision surgery. CONCLUSION: This study indicates that TURP and PVP have a similar durability after 5 years of follow-up.

Multiparametric Magnetic Resonance Imaging of the Prostate and Prostate-specific Membrane Positron Emission Tomography Prior to Prostate Biopsy (MP4 Study).

Background: Prostate-specific membrane antigen (PSMA) positron emission tomography/computerised tomography (PET/CT) is increasingly being utilised in the diagnostic pathway for prostate cancer (PCa). Recent publications have suggested that this might help identify those who can avoid biopsy. Objective: The primary objective of this study was to determine whether PET magnetic resonance imaging (MRI) fusion could negate the need to biopsy prior to prostatectomy in a selected population of men. Design setting and participant: Multiparametric MRI (mpMRI) for PCa is our standard of care prior to prostate biopsy. Biopsy-naïve men with one or more Prostate Imaging Reporting and Data System (PI-RADS) 4 or 5 lesions ≥10 mm on mpMRI were invited to undergo PSMA PET/CT prior to biopsy. Following ethics approval, 60 men were recruited between September 2020 and March 2021. The key exclusion criteria included a previous history of PCa and previous prostate surgery or biopsy. Outcome measurements and statistical analysis: A positive PET MRI fusion scan was defined as "consistent with" as per the Memorial Sloan Kettering Cancer Center lexicon of certainty, and concordance with biopsy results was analysed. Clinically significant PCa (csPCa) was defined as grade group (GG) ≥2 on pathology. A chi-square analysis was performed with statistical significance defined at p < 0.05. Results and limitations: A total of 71 mpMRI lesions were positive on 61 (86%) PET MRI fusion scans. Fifty-nine of 61 lesions biopsied confirmed csPCa in 54 (92%). Of five of 59 lesions for which either biopsy was negative or low-grade cancer was found, three had rebiopsy of which two were confirmed to have csPCa corroborating with PET MRI fusion and one was reconfirmed to have GG1 only. For the remaining two, both had another lesion elsewhere in the gland confirming csPCa, and hence rebiopsy was not performed. Ultimately, 56 of 59 (95%) lesions with a positive PET MRI fusion scan were confirmed to have csPCa. All GG ≥3 cancers had a positive PET MRI fusion scan. Conclusions: This prospective study of PET MRI fusion assessment of men with PI-RADS 4 or 5 lesion ≥10 mm on mpMRI confirms that the majority of men (95%) with a positive PET MRI fusion scan will have csPCa. This supports recently published retrospective data suggesting that selected men might avoid prostate biopsy prior to radical prostatectomy. Patient summary: In this research, we have confirmed that prostate-specific membrane antigen positron emission tomography/computerised tomography in combination with magnetic resonance imaging could have an important role in enabling a diagnosis of prostate cancer. Using the combination of these scans, we could confidently predict the presence of aggressive prostate cancer in some men for which treatment is warranted. This means that there are some men who could possibility proceed directly to having prostate cancer surgery without the need for a confirmatory prostate biopsy.

Retro-ureteral Small Bowel Herniation After Radical Cystectomy.

Small bowel obstruction caused by internal herniation under ureteric bands is a rare occurrence. Only 6 previous cases have been documented. This case report reviews the case of a 79-year-old male who presented to emergency with abdominal pain requiring subsequent laparotomy and release of internal herniation of bowel under ureter.

Bladder Contracture - A Rare and Serious Side Effect of Intravesical Bacillus Calmette-Guérin Therapy.

Instillation of intravesical bacillus Calmette-Guérin (BCG) is an effective treatment for non-muscle invasive bladder cancer (NMIBC). The high incidence of side effects may limit its tolerability in patients. Local side effects including cystitis and hematuria are common but generally self-limiting. Bladder contractures are a rare but serious consequence of BCG treatment. In this case, an 82 year-old male developed BCG reactivation and subsequent bladder contractures following transurethral resection of the prostate (TURP) three years post-BCG. To our knowledge, this is the first reported case of BCG reactivation post-TURP leading to the rare but serious effect of bladder contractures.

Box, cable and smartphone: a simple laparoscopic trainer.

BACKGROUND: Laparoscopic surgery requires different abilities to open surgery, and is challenging to learn within the confines of the operating theatre. With the development of laparoscopic surgery in modern surgery, the importance in improving these skills is becoming an increasing focus of surgical training programmes. CONTEXT: The assembly of the laparoscopic trainer and exercises was performed at the University of Sydney Clinical School located at Hornsby Hospital in Sydney, Australia. The objective was to design and construct a new concept smartphone box laparoscopic trainer that is affordable and replicable, and to demonstrate its usefulness in practising laparoscopic techniques to improve skills outside of the operating theatre. INNOVATION: The trainer was constructed using a personal smartphone, cardboard box, video graphics array (VGA) adaptor, VGA cable and a computer screen. Laparoscopic instruments and materials used for simulated task exercises were obtained from the operating theatre. Simulated demonstrations of simple laparoscopic tasks included suture handling, instrument knot-tying and anastomotic suture techniques. IMPLICATIONS: The smartphone box trainer is inexpensive (approximately $60) and took less than 20 minutes to build. The cost was almost entirely for the VGA adaptor. The box trainer was light, portable and easily transported to any setting that provided a computer screen. It is an inexpensive, easy-to-assemble, replicable model that benefits from the advanced technology of personal smartphones, and can be easily accessed as a useful tool in learning and improving laparoscopic techniques. Laparoscopic surgery requires different abilities to open surgery.
