Comparative analysis of the safety and efficacy of 1470-nm diode laser enucleation of the prostate and plasmakinetic resection of prostate in the treatment of large volume benign prostatic hyperplasia (>80 ml).

OBJECTIVE: To compare the efficacy and safety of 1470-nm diode laser enucleation of the prostate (DiLEP) with that of plasmakinetic resection of the prostate (PKRP) in treating patients with large benign prostatic hyperplasia (BPH > 80ml). METHODS: The clinical data from 211 cases of BPH (>80 ml) were collected for analysis. The patients were divided into two groups: the PKRP group (n = 118) and the DiLEP group (n = 93), based on the surgical method used. RESULT: The DiLEP group demonstrated significantly lower surgical time (p < 0.001), intraoperative bleeding (p < 0.001), bladder flushing time (p = 0.003), indwelling catheter time (p < 0.005), and length of hospital stay (p = 0.018) compared to the PKRP group. However, the quality of the prostatectomy was significantly higher in the DiLEP group (p = 0.005). The Qmax for the DiLEP group was significantly higher than that of the PKRP group (p < 0.05). Compared to the PKRP group, the incidence of urinary incontinence in the DiLEP group increased significantly 4 weeks post-surgery (p = 0.026), although the need for blood transfusion during surgery was significantly reduced (p = 0.037). CONCLUSION: Both DiLEP and PKRP are safe and effective methods for treating large-volume BPH. However, DiLEP offers advantages such as more thorough glandular resection, shorter surgical time, reduced bleeding, quicker recovery, and fewer complications.

Renal malignant solitary fibrous tumor: 1 case report and literature review / 重庆医学

Objective To investigate the clinicalmanifestations,imaging features,diagnosis and differential diagnosis,treatment and prognosis of renal malignant solitary fibrous tumor(SFT).Methods The clinical data in 1 case of rare renal malignant SFT were retrospectively analyzed.Referring to related literatures,the histological origin,pathological features,differential diagnosis,treatment and follow-up of renal malignant SFT were analyzed.Results The patient was preoperatively diagnosed as right renal clear cell carcinoma.Postoperative pathological examination diagnosed as low grade malignant SFT of right kidney.And immunohistochemistry indicated CD34+,BCL-2 +,CD68+,CD99+,vimentin,Ki-67 5％ +,SMA focal weakly positive.No recurrence or metastasis occurred after 4-month follow-up period.Conclusion Malignant SFT of the kidney is very rare,its diagnosis and differential diagnosis depend on postoperative pathological and immunohistochemical examination.Radical nephrectomy is the main option for malignant SFT of the kidney with good prognosis.
