Patients with proven urinary tract infection and/or known prostate cancer were excluded. PSA levels, International Prostate Symptoms Score(IPSS), prostate weight, post residual volume and pressure flow parameters were determined. A histopathological assessment of the presence and severity of inflammation was also performed.RESULTS: Patients had a mean age of 69.1 ± 8.6 years(45-90 years), with mean preoperative PSA levels of 4.7 ± 5.4 ng/m L(0.2-32.5 ng/m L) and IPSS of 15.7 ± 6.9(0-32). Mean Pdet Q max was 96.3 ± 34.4 cm H2O(10-220 cm H2O). The mean resected prostate weight was 39.4 ± 27.3 g(3-189 g). Correlations were observed between PSA(logarithmic) and resected prostate weight(r = 0.54; P < 0.001), PSA(logarithmic) and Pdet Q max(r = 0.17; P = 0.032), and resected prostate weight and Pdet Q max(r = 0.39; P < 0.001). Furthermore, low correlations were observed between PSA(logarithmic) and active(r = 0.21; P < 0.0001) and chronic(r = 0.19; P = 0.005) inflammation. CONCLUSION: In this study we showed a correlation between BOO(Pdet Q max) and PSA(logarithmic). Furthermore, we demonstrated a weak correlation between PSA(logarithmic) and active as well as chronic prostatic inflammation.展开更多

BPH is caused by unregulated proliferation within the prostate, which may cause physical obstruction of the prostatic urethra and result in anatomic bladder outlet obstruction (BOO). Transurethral resection of the prostate (TURP) has been the historical gold standard up till now to which all endoscopic procedures for benign prostatic hyperplasia (BPH) are compared with a mean hospital stay of three days. This surgery although efficacious has been related with increased morbidity and increased day case failure rates as compared to newer techniques. These shortcomings have prompted the utilization of newer methods like Transurethral enucleation and resection of the prostate (TUERP), Holmium laser enucleation of the prostate (HoLEP) and Thulium laser enucleation of the prostate (ThuLEP). This review will discuss the enucleation techniques, advantages and therefore the predictive factors for a successful day case prostate surgery. <strong>Materials and Methods:</strong> During this review, we discuss the newer techniques utilized in day case BPH surgery as well as the predictive factors for a successful BPH surgery, both enucleation, benefits and morcellation are covered also. <strong>Results:</strong> TUERP, ThuLEP and HoLEP have literature supporting the advantages of these techniques, which demonstrates its ability in day case BPH surgeries in specially selected cases with favorable factors and a 61% overall success rate. <strong>Conclusion:</strong> TUERP, ThuLEP and HoLEP Have proven to show favorable outcomes in day case BPH surgery with urologist’s experience, prostate size, duration of operation, age, use of anticoagulants, morning theatre list and ASA score being the key factors for a successful day case surgery.展开更多
