Safety and efficacy of transurethral resection of prostate glands up to 150 ml: a prospective comparative study with 1 year of followup

PURPOSE: We investigated the safety and efficacy of transurethral resection of the prostate (TURP) for prostate glands between 70 and 150 ml. MATERIALS AND METHODS: We prospectively evaluated 113 patients treated with TURP for benign prostatic hyperplasia. A total of 57 patients with a prostate volume of less than 70 ml were assigned to group 1, while 56 with a prostate volume of between 70 and 150 ml were assigned to group 2. Preoperative parameters considered in each patient were prostate volume, International Prostate Symptom Score (I-PSS), urinary flow rate measurement (Qmax) and post-void residual urine volume (PVR). Operative time, resected tissue weight and all complications were recorded. All patients were evaluated 3 months and 1 year postoperatively. Preoperative, perioperative and postoperative data on the 2 groups were compared. RESULTS: Each group achieved significant improvement in I-PSS, Qmax and PVR. Operative time was significantly longer in group 2 but the complication rate was similar in the 2 groups. Group 2 resulted in better improvements in Qmax and I-PSS. At 1 year of followup PVR was significantly lower in group 1 than in group 2. Multivariate analysis revealed that only age was a significant independent predictor of complications, and only age and initial Qmax were independent predictive variables of outcome. CONCLUSIONS: TURP for large prostate glands is a safe procedure without showing a different complication rate compared with TURP for recommended volumes. Patients with a baseline prostate volume of greater than 70 ml seem to achieve better improvement in obstruction and symptoms.

Randomized trial of the efficacy of tamsulosin, nifedipine and phloroglucinol in medical expulsive therapy for distal ureteral calculi

PURPOSE: Recent studies show the interesting efficacy of different drug combinations for the spontaneous expulsion of distal ureteral stones. We performed a randomized, prospective study to assess and compare the efficacy of 3 drugs as medical expulsive therapy for distal ureteral calculi. MATERIALS AND METHODS: A total of 210 symptomatic patients with distal ureteral calculi greater than 4 mm were randomly allocated to home treatment with phloroglucinol, tamsulosin or nifedipine (groups 1 to 3, respectively). Each group was given a corticosteroid drug and antibiotic prophylaxis with an injectable nonsteroidal anti-inflammatory drug was also used on demand. The primary end point was the expulsion rate and the secondary end points were expulsion time, analgesic use, need for hospitalization and endoscopic treatment as well as the number of workdays lost, quality of life and drug side effects RESULTS: The expulsion rate was significantly higher in group 2 (97.1%) than in groups 1 (64.3%, p <0.0001) or 3 (77.1%, p <0.0001). Group 2 significantly achieved stone passage in a shorter time than the other 2 groups and showed a significantly decreased number of hospitalizations as well as a better decrease in endoscopic procedures performed to remove the stone. The control of renal colic pain was significantly superior in group 2 compared with the other groups, resulting in fewer workdays lost. Group 3 showed lower analgesic use and decreased workdays lost compared with group 1. No difference in side effects was observed among the groups. CONCLUSIONS: Medical expulsive therapy should be considered for distal ureterolithiasis without complications before ureteroscopy or extracorporeal lithotripsy. The use of tamsulosin in this treatment regimen produced stone expulsion in almost all cases in a short time, allowing complete home patient treatment.     

Fluid overload syndrome: A potentially life-threatening complication of Thulium Laser Enucleation of the Prostate

Systemic fluid absorption frequently occurs during endoscopic surgery. When large volumes are absorbed, fluid overload is the result. The introduction of lasers allowed the use of normal saline (0.9% sodium chloride) in endoscopic prostatic surgery. This led to the disappearance of the transurethral resection syndrome; however, the fluid overload of normal saline can cause the onset of several catastrophic effects. The present study aimed to evaluate the incidence, sign and symptoms severity of fluid overload in a large series of men who underwent Thulium Laser Enucleation of the Prostate. Between December 2014 and February 2020, 633 men underwent the procedure. Seven patients (1.1%) had symptomatic fluid overload. Two patients developed severe pulmonary oedema, which required oral intubation and admission to the intensive care unit. Two patients required delayed morcellation. The analysis of our series highlighted that old age, large prostate volume, prolonged operative time and prostatic capsular perforation influenced the onset of fluid overload syndrome. Urologists should be aware that fluid overload might be a potentially life-threatening condition and should be early recognised. Surgery should be interrupted as soon as it occurs to avoid severe pulmonary oedema.
