Pilocarpine in postoperative urinary retention, as shown by the clinical observations of Lampert a (Zentr. F. Chir., 1926, No. 8), provides excellent services: already a single injection into a vein of a 1.01% solution of pilocarpine (maximum single dose 0.02 , pro die 0.05 pure pilocarpine), even after a 24-hour delay, gives spontaneous urination in 5-15 minutes.

ABSTRACT The concept of an oestrogen surge as a prerequisite for successful decidualization of the progravid uterus and consequently nidation in the rat was tested. Experiments were designed to see whether administration of an oestrogen antagonist at specific times would block decidualization (and nidation); whether the ovary was the source of the oestrogen, and whether a single dose of oestrogen, in the absence of the ovary (if the ovary is the source) would allow the uterus to respond to a decidualizing stimulus. It was found that when given prior to the surge, the oestrogen antagonist prevented decidualization and interfered with nidation. The ovary is thus the source of the oestrogen; and a single injection of oestradiol can act as a substitute for the surge.

Objectives: Postoperative urinary retention (POUR) is influenced by many factors, and its reported incidence rate varies widely. This study aimed to investigate the occurrence and risk factors for urinary retention following general anesthesia for endoscopic nasal surgery in male patients aged >60 years. Methods: A retrospective review of medical records between January 2015 and December 2019 identified 253 patients for inclusion in our study. Age, body mass index (BMI), a history of diabetes/hypertension, American Society of Anesthesiologists (ASA) classification, and urologic history were included as patient-related factors. Urologic history was subdivided into 3 groups according to history of benign prostate hyperplasia (BPH)/lower urinary tract symptoms (LUTS) and current medication. The following was analyzed as perioperative variables for POUR development: duration of anesthesia and surgery; amount of fluid administered; rate of fluid administration; intraoperative requirement for fentanyl, ephedrine, and dexamethasone; postoperative pain; and analgesic use. Preoperatively measured prostate size and uroflowmetry parameters of patients on medication for symptoms were compared according to the incidence of urinary retention. Results: Thirty-seven (15.7%) patients developed POUR. Age (71.4 vs 69.6 years), BMI (23.9 vs 24.9 kg/m2), a history of diabetes/hypertension, ASA classification, and perioperative variables were not significantly different between patients with and without POUR. Only urologic history was identified as a factor affecting the occurrence of POUR ( P = .03). The incidence rate among patients without urologic issues was 5.9%, whereas that among patients with BPH/LUTS history was 19.8%. Among patients taking medication for symptoms, the maximal and average velocity of urine flow were significantly lower in patients with POUR. Conclusions: General anesthesia for endoscopic nasal surgery may be a potent trigger for urinary retention in male patients aged >60 years. The patient’s urological history and urinary conditions appear to affect the occurrence of POUR.

1 Effect of the diphenyl ether herbicide fomesafen on liver preneoplastic changes and porphyrin biosynthesis was examined in male C57BL/6J mice (0.23% in the diet for 14 months) and ICR mice (0.3% in the diet for 50 weeks). Fomesafen treatment resulted in preneoplastic changes (liver nodules and foci of altered hepatocytes) in both strains, uroporphyria developed only in ICR mice. 2 Iron pretreatment (600 mg/kg as a single dose) accelerated the development of fomesafen-induced preneoplastic changes in both mouse strains. The number of foci containing altered hepatocytes, as well as the number and size of liver nodules, were increased in iron-pretreated animals. 3 A single injection of iron induced marked uroporphyria in C57BL/6J mice after 14 months (liver porphyrin content 102 nmol/g). This uroporphyria was further potentiated by fomesafen administration (208 nmol/g). 4 In ICR mice, liver histology was apparently normal after a 3 month recovery from fomesafen treatment (0.32% for 9 months). Liver porphyrin content (260 nmol/g) started to decrease immediately after fomesafen withdrawal, but was still significantly elevated after 3 months (5 nmol/g), as compared to controls (1 nmol/g). 5 It is concluded that the toxicological evaluation of fomesafen should focus on liver porphyrin biosynthesis.

Suggested Technique

Objective: To assess the efficacy of hemorrhoidectomy with Milligan-Morgan technique in the author’s modification.Methods: Results of surgical treatment of 558 patients aged 21–72 years with complicated hemorrhoids of III–IV stage were analyzed. The group of clinical comparison (207 patients) was operated according to standard scheme, the main group (351 patients) – according to author’s technology with modified technique for treating the hemorrhoid bolus using betamethasone.Results: When using the author’s technique, a more significant decrease in postoperative pain syndrome severity was achieved: injection analgesics were not required already in a day, and after 6 days the pain syndrome was stopped in all cases. Only three patients (0.9%) demonstrated an acute urinary retention up to two days. The group of clinical comparison maintained a longterm (up to three months) pain syndrome; postoperative urinary retention was registered in 38 cases (18.4%); 9 patients (4.3%) developed blood loss in the area of surgical intervention.Conclusions: Suggested technique of surgical treatment for hemorrhoids is quite effective, simple and can be implemented in any surgical inpatient facility.
