Low-frequency electrotherapy for female patients with detrusor underactivity due to neuromuscular deficiency.

INTRODUCTION AND HYPOTHESIS: The aim of the study was to assess the efficacy of low-frequency electrotherapy (LFE) for female patients with early-stage detrusor underactivity (DUA) due to neuromuscular deficiency. METHODS: A total of 102 female patients were divided randomly into four groups: LFE-NC (normal compliance), LFE-LC (low compliance), CON (control)-NC and CON-LC. Patients in the LFE-NC and LFE-LC groups received LFE, and those in the CON-NC and CON-LC groups received conservative treatment. Urodynamic evaluation was performed before and after treatment. RESULTS: After treatment, 82 % of the LFE-NC regained detrusor contractility, whereas only 2 (8 %) of the CON-NC had normal detrusor contraction. None of LFE-LC or CON-LC regained detrusor contractility (p < 0.01). The per cent of LFE-NC who relied on catheterization for bladder emptying decreased by 43 % (p < 0.01). Those in the LFE-LC, CON-NC and CON-LC groups decreased by only 4, 12 or 0 % (p > 0.05). CONCLUSIONS: LFE was more effective for DUA patients with normal compliance; these patients benefited from LFE, but DUA patients with low compliance did not.

[Treatment of 58 cases of penile squamous cell carcinoma].

OBJECTIVE: To search for rational and effective treatments for penile squamous cell carcinoma (PSCC). METHODS: We retrospectively analyzed the clinical data of 58 cases of pathologically confirmed PSCC, focusing on the treatment methods. RESULTS: Based on Jackson Staging, 25 of the 58 cases fell into stage I, 18 stage II, 11 stage III, and 4 stage IV. Fifty-three of the patients were treated by surgery, of whom 43 underwent limited resection of the tumor or partial amputation of the penis, and the other 10 received total penis amputation plus perineal urethrostomy and clearance of lymphoglandulae iliacae and inguinal lymph nodes, with the lymphoglandulae iliacae positive in 1 case and the inguinal lymph nodes positive in all. Thirty-seven cases received neoadjuvant hormonal therapy (thermotherapy plus chemotherapy) and combined postoperative chemotherapy, 12 postoperative chemotherapy only, and 4 merely surgery. Five of the total number underwent chemotherapy and/or radiotherapy without surgery. The 2-5 years follow-up of 48 patients found recurrence in 4 cases of partial penis amputation within 2 years, 4 deaths within 2 years, 7 deaths from 2 to 5 years. The 2- and 5-year survival rates were 91.7% and 77.1%, respectively. Ten of the cases were lost in follow-up. CONCLUSION: Surgery + neoadjuvant hormonal therapy + postoperative chemotherapy and/or radiotherapy is an effective method for PSCC, but whether it can reduce the recurrence of PSCC and improve the survival of the patients remains to be further studied.
