Incidence of and risk factors for postoperative urinary retention in fast-track hip and knee arthroplasty

Figures & data

Table 1. Numbers of elective fast-track THAs and TKAs where urinary bladder catheterization was performed postoperatively, and their distribution between departments

	Department A (n = 230)	Department B (n = 226)	Department C (n = 310)	Department D (n = 296)	Total (n = 1,062)
Intermittent catheterization	81 (35.2%)	127 (55.2%)	132 (42.6%)	89 (30.0%)	429 (40.4%)
Repeated intermittent catheterization	4 (1.7%)	16 (7.1%)	14 (4.5%)	9 (3.0%)	43 (4.1%)
Indwelling catheter because of POUR	0	2 (0.9%)	0	3 (1.0%)	5 (0.5%)
Indwelling catheter not because of POUR	4 (1.7%)	1 (0.4%)	1 (0.3%)	2 (0.7%)	8 (0.8%)

POUR: postoperative urinary retention.

Urine volumes evacuated at the first intermittent catheterization postoperatively (n = 414).

Table 2. Distribution of sex, type of arthroplasty, and anesthetic technique in catheterized and non-catheterized patients

	Catheterized (n = 424)	Non-catheterized (n = 630)	p-value
Sex			0.2
Male	159 (37.5%)	262 (41.6%)
Female	265 (62.5%)	368 (58.4%)
Type of arthroplasty			0.5
THA	228 (53.8%)	352 (55.9%)
TKA	196 (46.2%)	278 (44.1%)
Anesthetic technique			0.04
Spinal	387 (91.3%)	549 (87.1%)
General	37 (8.7%)	81 (12.9%)

THA: total hip arthroplasty; TKA: total knee arthroplasty.

Table 3. IPSS grouped according to severity, and compared between non-catheterized and catheterized patients, and also between patients catheterized for bladder volumes < 500 mL or ≥ 500 mL

	IPSS 0–7	IPSS 8–19	IPSS 20–35	p-value
All patients, n	603	367	70	0.1
Catheterized	226 (62.5%)	166 (45.2%)	26 (37.1%)
Non-catheterized	377 (37.5%)	201 (54.8%)	44 (62.9%)
Catheterized patients, n	220	162	25	0.5
BV < 500 mL	60 (27.3%)	40 (24.7%)	8 (30.8%)
BV ≥ 500 mL	160 (72.7%)	122 (75.3%)	18 (69.2%)

IPSS: international prostate symptom score.

Missing data: IPPS was missing for 6 catheterized patients and 8 non-catheterized patients. Evacuated bladder volume was missing for 10 catheterized patients.
