“…5,[7][8][9] Retention rates with TTPB varying from 2% to 39.4% have been previously reported. 2,11,[13][14][15][16] We carried out this data analysis as we were concerned by the number of men experiencing retention post-TTPB, though our rate of 17% does not compare unfavourably with that reported by Merrick et al of 39.4%. 13 In our series, urinary retention usually occurred immediately following the procedure, although one patient with presumed chronic urinary retention presented five days later.…”

“…18 A low retention rate appears to be associated with fewer cores taken and avoidance of the TZ. Vyas et al demonstrated a retention rate of 2% employing a sector biopsy method using a minimum of 24 cores in glands < 30 cc, up to a maximum of 32 cores in larger glands; 16 in this scheme the TZ is deliberately avoided in order to reduce the morbidity of the procedure, but must therefore risk missing cancers confined to the TZ. In a series of 529 patients undergoing TTPB, 45.3% of prostate cancers had TZ involvement, although only 4.6% of cancers were confined to the TZ.…”

Background: As greater numbers of transperineal template prostate biopsies (TTPBs) are being performed, we have noticed that a considerable number of patients experience urinary retention post-procedure. We wanted to quantify this, and to examine factors that might predict which patients will experience retention. Patients and methods: Data analysis was performed on a prospectively maintained database on 93 consecutive patients undergoing template prostate biopsy over a 12-month period. Results: Mean patient age was 66 years (range 46-79). Mean prostate-specific antigen (PSA) was 8.34 ng/ml (1-31), mean transrectal ultrasonography (TRUS) volume 51 cc (10-133) and mean number of cores 52 (11-84). Twenty-five patients had muscle relaxant as part of their anaesthetic (27%). Fifteen patients had haematuria immediately postprocedure (16%). Twenty-six procedures were performed by a urology trainee (28%). Sixteen patients experienced retention post-template biopsy (17%). Their mean age was 67 years, mean PSA 8.9 ng/ml, mean TRUS volume 68 cc and mean number of cores 58. Of the retention group, 10 patients had muscle relaxant (63%), one patient had haematuria (6%) and four procedures were performed by a trainee (25%). Factors that significantly correlated with retention were TRUS volume (r = 0.36, p = 0.0004) and the use of muscle relaxant (r = 0.37, p = 0.0003). Age, PSA, number of cores taken, haematuria post-biopsy, and intra-operative furosemide, paracetamol, diclofenac, morphine and dexamethasone were not correlated with retention (p > 0.05). Conclusion: Patients with higher TRUS volumes are at increased risk of retention post-TTPB and should be counselled accordingly. Due to anti-muscarinic effects, muscle relaxants should not be used.
